Design a handout with a single bitcoin address and key along with instructions to redeem the private key. The handout could be loaded with a little as some bitcents or whatever, just to give away as a bitcoin awareness project. We could hand them out or even just stash them in places where they may be found. https://www.bitaddress.org/ is a good way to generate the address, and then we can just load them from a smarphone app. Any thoughts?
Sounds like it's along the lines of what the 'operationbitcoin.org' thing is working on. And a reasonably good idea.
I hacked out what is probably a serviceable solution for generating handouts which you are welcome to use if you need it. One should be able to put just about any URL you like on them with potentially a tiny bit of python hacking (if you wanted to put full instawallet-type URLs for instance and needed to shrink down the text size since I did not make it auto-adapt.)
I guess I'll just put a pointer to it here rather than a PM.
