Man, a federated money transfer service would be JUST THE THING right now. Maybe use blockchain, maybe don't, but if someone could just make that happen that would be amazing. :/
For bonus points, have some kind of an integrated market feature or something. Pretty please? :P
@xeno I have not! I'ma look though. XD
@xeno Aaaargh it won't load! I'll have to check back later. :(
@Angle have you seen https://www.openbazaar.org? (Never used it myself, though...)
