dont some applications sort of rely on the named piped/socket being
unique on a cluster filesystem as a part of their locking system.

i wont want to use pipes/socket as a general purpose communication
system across afs though.  there are probably better choices.  i just
want a globally consistent reference in the filesystem to a local/client
context.
