I've found some time to begin implementing a remote-helper[1] this week. Plugging in a call to "bzr fast-export" made cloning a repository with "git clone bzr::url" and pulling new revisions in with "git pull" work with minimum effort.

However, as reported in this bug[2], the fast-import path to push commits back to bzr is broken in the bzr plugin. Once we get this working, we should be able to round-trip.

Doing "git pull" currently exports all history from the Bazaar branch to incorporate the needed commits in the git repo. This is really suboptimal, but I thought having something that works before making it work right would help me get some insights on the remote-helper's code.

The very cool thing about making this into a remote-helper instead of a git command in itself, is that we won't have to redisign (and possibly re-implement) the command line interface, since git will be calling the remote-helper with the right commands at the appropriate time.
