Well, data have to be transferred in some way.
What you need is more or less what I was looking for some time ago: a
caching fileserver proxy.
But the only thing I've found is an active-active cluster. Too bad it
requires a shared disk (even if it seems NBD could avoid that). But for
this you'd need twice the disk (one copy per site, then ust the "diffs"
travel throught the slow link -- so writing a file is slow, but reading
it is fast).
Maybe setting up two msdfs shares (is it well supported by Samba?) could
help. But the two servers have to be kept synchronized "in some way"...
