My only question about doing this is:  Can you really license your changes
to Darcs as BSD3 where they are changes to existing GPL'd code?  I thought
that the GPL applies to derivative works is why I ask.  So, if I'm
understanding it correctly, then I think what you're trying to do only makes
sense for 1) bits where you are the original author of the that bit 2)
modifications to darcs where the previous authors agree to release their
changes as BSD3.

Another case I'm unclear about is when you are the OA (original author) of a
chunk and then someone who hasn't agreed to relicense as BSD3 changes
something in your code.  In that case, I think you'd have to revert (and
rewrite) instead of just rewriting if you want to keep it BSD3.

Just something to think about.  I don't object to any of this relicensing,
I'm just trying to understand how it works.
