I help run a large open source org.

I'd be interested in using a service like this, but only if it offered a good way to crowd-source the funding for bounties.

Ideally we'd be able to accept proposals for bounties, and then have a Kickstarter-style mechanism for the funding, which is held in escrow and then released to whoever completes the bounty.

Feel free to email me if you'd like to chat more :)
