Command line tool: offline transactions, download blockchain, privkey sign/verif

[genjix]

I've built a bunch of tools that allow us all the whizz-bang toys like offline transactions, piping a transaction to multiple sends, a flyweight client, piping transactions over network shares to a single bitcoind and whatever guile schemes you can imagine. In shell we trust.

- Download blockchain into an SQL database.

- Query SQL database to find the balance of a bitcoin address.

- Create new private keys.

- Sign and verify data using those private keys.

- Get bitcoin address from private key.

- Create and save a transaction to a file, pipe, network share, USB stick, whatever.

- Load and send a transaction to a bitcoin node.

All nice and well but how about something that is easy to use and work on Linux / Windows and allows the user to read those damn private keys so the coins can never be lost in case of HDD crash etc. !?

This is really good stuff.

Would I be able to query the database and get unspent outs for an address ?

Is the downloader just a one-time-app that connects to the network, downloads all blocks and exists, so that you must run it every one in a while to keep the blockchain new, or is it a service-type-thing that actively participates in the bitcoin network and downloads new blocks automatically as they come?

Does it remove blocks from the database on an update in case there is a chain split?
