What about generating transactions offline, then sending them from a public location, or uploading them to a website, etc? Is there a way to do this?
i have a proof of concept/platform for creating transactions using plain text/files/QR codes using the BitcoinJ client. The transaction can be forwarded from a relay client, which could be anywhere with an internet connection. I've been working on it in my spare time for the last couple of months and I've hinted at it on the forums every once in a while. The actual transacting is a bit light on testing and it needs more work on the receiver/relay side. Some of the bigger issues I haven't even begun to address are double spends attempts (accidental or intentional), transaction revocation, and other fun stuff I probably haven't thought of yet. I've been spending the last few weeks setting up tools in preparation of opening up development and doing an initial public release. Look out for in the coming weeks/months.
