should work with drbd "just fine",
if you manage the administrative overhead.
only "client computers" would ever go "drbd Primary",
and the "central secondaries" should live on (several)
powerful storage (clusters).
in the architechture I envision right now, data would be accessible only
on one client computer at a time, so you probably need to (educate and)
enforce users to have at most one login at any time.
which you should do anyways, if you allow offline operation,
regardless of technology used.
you also need to think about authorization and authentication,
as well as encryption, probably, as by default,
DRBD is a "clear text" (well, binary) protocol.
how many clients computers are we taking about?
how much storage,
if you are interessted, we (Linbit) can give you a call
and discuss how we can support you in rolling this out.
just drop me a note.

I know that people use AFS on top of DRBD,
but that is for having the AFS server highly available.
so make your AFS server a DRBD HA cluster,
and have your clients be "standard" AFS clients.
it appears to work just fine.
I have no personal experience with AFS, though.
