I'm not sure whether the following is a legitimate concern or not, 
because I don't understand bzr internals enough, and haven't been 
following this thread quite closely enough. Seems worth mentioning, though.

The potential problem I see with this is when the same on-disk store is 
used by multiple clients with different operating systems. Samba shares 
of FAT32 drives, burnt CD-ROM archives, and plain-http repositories come 
to mind as ways this could happen.

It would be somewhat tragic if you couldn't burn a backup of a bzr repo 
from a Win32 box, restore it to your Linux box, and have it work.
