Thanks for CCing me. I've done some tests for the initial "bzr branch"
over a 3 Mbit/s connection:

   bzr://bzr.savannah.gnu.org/emacs/trunk
   6949.356  Transferred: 469739kB (67.6kB/s r:469659kB w:80kB)

   nosmart+bzr://bzr.savannah.gnu.org/emacs/trunk
   2919.117  Transferred: 524353kB (179.7kB/s r:524162kB w:191kB)

So the transferred data volume is slightly higher in the second case,
but IMHO it more than pays off in terms of total time.
