Not really -- the use of rsync for the objects fails horribly on slow links when the project scales in the number of commits. The rsync protocol has to transfer the names of each file and some information about it, and that information isn't delta compressed. This is where kernel.org is falling over, as well as what makes the kernel tree very painful to use over a dialup modem link.
