   is there any reason to *not* have a server also be a client?  (doesn't
   this sound too much like the hair club for men: "i'm not only a
   server ... i'm a client!")

We have noticed severe performance degradation when writing to a
volume that is stored on a machine from that same machine.

I don't know whether this is just us, or a general problem that is
known to Transarc.  It would seem to me that if the Kernel has to
context switch over and over between the AFS client processes and the
AFS server processes, it's going to get a bit bogged down....
