On SunOS and Ultrix, "/usr/etc/showmount -e <server>" will display the
export list of <server>.  It includes file systems you don't have access
to, so you'd have to use awk, perl, or something like that to restrict it
to the accessible file systems.

I don't know whether AIX or Mach have showmount.  But I think it's
available in the public BSD sources.  You should be able to modify it to
discard inaccessible file systems pretty easily.
