Let's say there is a scenario where I am one of two different people who claim to be responsible for sending bitcoins for a purchase.  How could I prove to the merchant that those bitcoins came from my wallet and nobody else's?

Something like this is possible (I've been thinking about doing it, although I have higher priority things on my TODO list):


bitcointools+openssl (see grondilu's thread about "a shell-script implementation of bitcoin) are enough to do all all the public/private key, file-creation, and signature generation/checking stuff.
