I'm not that familiar with bzr, but the idea is that once this 
conversion is done, merges could be automated on some way, except for 
conflicts.  My dream is some sort of cron job that merges from Emacs 
back into a CEDET integration branch, and also from the CEDET trunk into 
the integration branch, and warns when a merge fails. When Emacs wants 
to sync back, the merge would be quite simple from the integration 
branch at any time.  Periodically, someone could merge the Emacs 
integration branch into CEDET trunk.

The challenge is just finding someone with the right skills and time to 
help out.
