I don't buy the "needs". But it would certainly be interesting to have
as much compatibility as possible, for instance, as a first step, being
able to push/pull between darcs and git repositories.

This comes in three degrees:
- -Ok as long as one side is private (this should be fastconvert + some UI
glue, would make most ghc hackers' dilemnas moot)
- -Ok as long as there is a centralized bridge between them: each
patch/commit crosses the border only once (a bit harder)
- -Fully distributed (there lie semantic problems and darcs/git impedance
