Sure, here you go.

Does that help?

Good to know - thanks!

Some clients do have that feature - if I'm not mistaken: Electrum, Armory, Blockchain.info wallet.

This command-line tool displays transactions as they are happening on the blockchain.
It's similar to a network trace, but for blockchain activity. It has the ability to automatically flag large transfers.  It can be useful in identifying interesting patterns in transactions.

Warning: watching the live blockchain action can be hypnotic!

Features:
- Print new transactions to the console, in the following format:
   UTC Time, Total Amount (sum of all outputs), Main recipient, Transaction Fee
- Big (50+ BTC) transactions and extreme fees are flagged.
- Also shows "new block" events, with the corresponding block reward
- No private keys, admin privileges, or credentials of any sort are needed.
- 100% Python -> runs fine on OS X, Linux, Windows and Android!
- NEW August 2014: transaction type guessing engine  (in private beta build only)
- Low-latency encrypted websocket connections
- Extremely light on resources and bandwidth
 
I will be adding new features and parameters on a regular basis.


The current data source is the blockchain.info websocket API. Direct local bitcoind support, while a little more complex, could also be implemented in case there is enough demand for that.

Many thanks for your support - donations will help me continue development!

As a little bonus, you will be treated to a colorful ASCII easter egg (in the Windows build only, for now), if chainsnort sees a tip being sent to my tip jar [1111127SpvabYpoeDoiz5L7QPkfiSh2Q] - The easter egg changes depending on the size of the transaction

I also have a separate edition with some features that are useful for forensic and technical investigation purposes. I'm not releasing it at the moment but PM me if interested.

Legal stuff:
I share the source code of chainsnort for educational and reviewing purposes only. If you plan to reuse portions of the code in commercial, academic or government projects, please contact me.
                    
Also, I am developing this on my free time and with a VERY limited budget, so i welcome any donations. Also, all donators are entitled to a special color edition of chainsnort.  (Proper website coming soon)

Where do you get this idea from? Nowhere in this transaction do I see 3.40 BTC for fees.

Thanks, I'll wait for a couple more days in case other potential candidates show up. 

OK, it seems that earlier versions of the iOS app save the wallet file there:
/private/var/mobile/Documents  

The file should be named "wallet.aes.json" or similar. Inside the file, look for the "priv" values.
If they are encoded in an exotic format, let me know and I should be able to help with the decoding.

EDIT: if you find nothing in the above path, the following commands are also worth a shot:

find /var/mobile | grep -i wallet

or

find /var/mobile -iname \*wallet\*

The older versions of the app did store the password in plaintext on the device.
I don't have an iOS device at hand, but here is the path for Android: /data/data/piuk.blockchain.android/shared_prefs/piuk.blockchain.android_preferences.xml

Perhaps the iOS version used a similar scheme. Try looking for a blockchain preferences file on your device.

No, it currently doesn't have those features implemented.
And yes, I think Python would be a good option as well - actually the very first prototype of Deep Space Vagabond was a quick Python hack done in late 2011.

Yes, Electrum regenerates all addresses, including change, from the seed.
This is what deterministic wallets are about, and is one of the major differences between Electrum and MultiBit or Bitcoin-Qt (although they are also working to implement deterministic wallets in future versions.)

Glad to see that you're interested!

It's mostly written in AHK (are you familiar with it?), as I wanted to experiment a little bit more with that language, and it allowed for real quick GUI prototyping...  Also, as stated in the original post, the actual address generation is delegated to vanitygen (with samr7's permission).

Could you elaborate on what you would plan to do with it?

Although I still have tons of ideas to make Deep Space Vagabond more fun, I just don't feel motivated enough for implementing them and maintaining this project anymore. However, I don't want to see it die, so if anyone would like to take it over, let me know. Note that I will consider the online reputation of any interested parties as I wouldn't like this project to fall in the wrong hands.

At least the guy is saying the truth: "ascending order" -> this means his own site (first in the list) is the least trusted in his opinion

Updated... 24 Electrum servers now - including the first one in Australia!

If you notice any errors, just let me know.

Well for the CPU-intensive stuff (EC math), it uses OpenSSL, which is a compiled and optimized library.

First, are you trying openssl on Windows or Linux? I've noticed that it does make a difference, in some cases.

This wiki page has it (last column in the table):

Indeed that's where I got the clue from. Unless I'm missing something, this could represent a risk as I stated above. Of course, this risk is only present when using vanitygen as a bulk generator with no external seed, which it is fair to say is not its primary intended use.

Anyway, after double-checking my measurements, it seems that Bulkgen IS surprisingly even faster than Vanitygen (for bulk generation.)

EDIT: I might be wrong about Vanitygen's vulnerability. From the above quote, it seems that it also resets the starting point whenever a match is found (which is, all the time when run with the '-k 1' arguments).  If anybody with enough experience could confirm this, it would be great.  

Some users (mostly merchants and exchanges) have expressed the need to generate thousands or millions of addresses at once. I've looked at the options available and was surprised to find they were all quite slow, which is why I have knocked up a new little command: Bulkgen (not released yet.)
Below are some rough figures from my offline machine (a very old, VERY SLOW Win XP netbook.)

I will try to run the same tests on a faster machine soon.


Time required to generate 1000 addresses:

Did I forget any other tools?


Bulkgen is an open-source bulk address generator tool, based on OpenSSL and a public domain library. It will be released for Windows only in the beginning. People will be welcome to port it to other platforms (which should be quite trivial).


Notes:
  
1. As far as I can see, bitcoind's getnewaddress does not only generate a new address, but also adds it into the wallet database, which takes extra time of course.
 
2. The command "Vanitygen -k 1" runs much faster than all other options, but I think this comes at a heavy cost: If one private key of the batch is compromised, all others becomes vulnerable, due to the fact that vanitygen only performs a new EC multiplication once every 10 million addresses, which is what allows it to be so fast (Please correct me if I'm wrong).

Why not simplify your regexes as follows:

rather than: 1[a-zA-Z0-9]{31}
try:            .{32}

and so on...
