I have always considered DFS/AFS to be pretty much the same thing. And yes,
AFS is pretty darned good. But I haven't heard anything dramatically better
about the DFS version vs. the freely available AFS version.

Never heard of them. Specifically, never heard of anyone building clusters out
of AIX machines.

AFS can definitely be used over Gig links. Works quite nicely.
