If there is enough disruption in the pools for a couple weeks would the difficulty drop?   How much of the total network  hash rate is made up in pools?
Even if you use Bitcoin through Tor, the way transactions are handled by the network makes anonymity difficult to achieve. Do not expect your transactions to be anonymous unless you really know what you're doing.

all bitcoin transactions are recorded in the blockchain, if you sent it on its way then it irrelevant if their client died or not
look your transaction up on http://blockexplorer.com/

It's not irrelevant if you've emailed them about it and received no response from them in 10+ days.

I accidentally duped a 10 BTC transaction to a merchant using mybitcoin.com and am yet to get any response from them (mybitcoin.com, not the merchant).


Don't use MyBitcoin?  The whole strength of Bitcoin is that it is 100% decentralized; why give that up?

Translation: most of it.

But sometimes it seems it doesn't work.

Do you mean boycott all merchants that use mybitcoin.com to accept payments?

That will drastically reduce the take-up rate for new bitcoin merchants.

Not every store owner knows how to set up a wallet on their own server.

On the side note, Bitcoin Signature Generator was subject to an attack a week ago. I got hundrets of new registrations with names like:

Code:
1 UNION ALL SELECT null,null,null,null,null--
999999.9 UNION ALL SELECT 0x31303235343830303536--
/\\../\\../\\../\\../\\../\\../\\../etc/passwd
${@print(md5(acunetix_wvs_security_test))}\\
sample@email.tst\' and sleep(4)=\'
etc.

Attacker's IP was: 124.148.255.198
UA String: "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727) Havij"

"Havij" is a popular vulnerability scanner. This probably means the attacker is a script kiddie who is bored.

It is pitch black. You are likely to be eaten by a grue.

Probably not by much.  People will either switch to another pool or solo mine until the pools come back up.  The network doesn't care if the blocks come from pools or not.

Tips are always welcome and can be sent to 1CZ8QgBWZSV3nLLqRk2BD3B4qDbpWAEDCZ

Thanks to ye, we have the final piece.

Indeed.  If you have a website with a web form, you will be under attack all the time from these things.  People just leave them running day and night, crawling the web, and looking for vulnerabilities.  I've seen normal sites under attack daily from these.

When MtGox got DDOS'd, it was hackers demanding a ransom. I wouldn't be surprised if many pool operators are getting similar demands.

Come to think of it, bitcoin might just be the perfect way to accept a ransom of any kind.
