I like franky1's suggestion. The "other" computer could handle more than just checking for payments. On the other hand, sometimes the "other" computer might be temporarily unavailable. In that case, it's useful to still be able to give out a payment address immediately.


While I do like money, the truth is that what I'm describing is simple enough that I wouldn't charge anything for sharing it. Also, the things I never did (dealing with images/QR codes) I'm not very interested in doing at the moment. I'll see if I can isolate a few lines of mysql and php that anyone can copy to start from. If I can, then I'll post it here.
