  Huh? You can reuse the objects with my approach as well. Actually, it
is automagically done so.

  With proxy repository, you would still need a server-side setup to
maintain that repository, and specialized client-side porcelain to fetch
from it. My approach initially requires some core changes (which aren't
very pretty as it is but are not very fundamental or logically intrusive
either) but in the longer run it pays off since you don't need a
convoluted server-side setup for that.
