I'm leaning towards doing this now.  We might as well do it right now, 
since we won't get the chance again.  (Malcolm - sorry for missing your 
suggestion the first time around, I did track it down in the first round 
of discussions.)

John - I'm happy to help if you let me know what needs to be done.  As 
far as making new branches for 6.6 goes, I'm assuming we'll deal with this.

Having both repos is starting to hurt now, it's a fiddle to move patches 
from darcs to CVS to commit them.  So I want to throw the switch ASAP; 
I'm pretty certain we've dealt with any blocking problems now.  So once 
we've got the libraries re-tailored, and tested the nightly builds with 
the new setup, I think we could switch.
