I concur with what Claire and Jonathan said.  And, I also feel the trouble
that the current msync admins go through during such massive updates.  The
"chasmd" project that Karan pointed to in another thread is really
interesting, and would make life easy if done properly.

We also don't mind having a push update request.  But, we already update
every 2 hours, and can even go for every hour, if needed.  Would a push also
be required for such frequency?

rsync is a great tool, but it hogs down the bandwidth of the server it is
syncing from.  Is it insane to think about other file-sharing protocols for
syncing, like BitTorrent, for keeping your mirrors upto date?
