sorry, I know I'm always dragging up old shit, but..
am I the only one that thinks it looks like quickcoin is trying to get bought by facebook?
it would be a nice payday for quickcoin, and it would offer facebook a nearly turn-key solution to offer facebux.
I'd recommend they design it as an off-chain wallet where your facebux are held and transferred from user to user.
with sidechains or treechains or whatever it should be possible to build it in an open, trustless manner. though I suspect facebook will build it as a black-box type of off-chain abomination a'la mtgox.
interesting times.
