Now - if we can get Issues doing the same thing by building on top of something like YABT or some other text-based approach to issue tracking, that'll be awesome.
One of the reasons I wrote it instead of extending ticgit was that I wanted something entirely independent of any VCS. All stuff I need to get in a readme, though. :-)
I'm curious about using CouchDB, actually. It has similar versioning and replication features to git.
I looked at Fossil for this reason (distibuted src/wiki/issues), but wasn't convinced that it was a real Mercurial or Git replacement for source control, so I gave up for now. Maybe something like Bugs Everywhere will do the trick.
