Discuss possible designs for an external program that discovers bridge addresses to tell Tor about them

This ticket is part of sponsor F deliverable 7. Before we can come up with a recommended approach for an external program that discovers bridge addresses to tell Tor about them, we need to discuss possible designs.

Mike said he's going to take the lead on the discussion. Back in December we agreed on February 13 as the deadline for the discussion. Maybe we need a new deadline, but one that still leaves time for writing proposals and starting to implement them.
