SelfStarter is a cool open source clone to KickStarter. For now, it only accepts Amazon Payments (which do not support non-US customers!).
I want to use it to kickstart a small hackathon project we're doing at my workplace (it's a very cool project btw, will post if we end up launching the selfstarter).
In case anyone is interested, here is the
pull request. I don't know if the Lockitron guys (developers of SelfStarters) know anything about Bitcoin, but I hope they don't reject the request on the spot.
