Actually the AT&T RFS protocol does use XDR from Sun to provide
byte-order independence on the wire (and makes specific reference to Sun
XDR in the protocol specification).  RFS is a remote procedure call
style protocol, but not in the Sun RPC sense though (thankfully! ;-).

As for full OS heterogeneity, well that's obviously not possible if
you're trying to maintain full Unix filesystem semantics (eg. chroot,
devices, etc.).

Yes, SunOS-4 RFS did work very well -- just as well as any RFS
implementation.  Indeed some friends of mine at HCR way back when were,
after lots of tuning, able to demonstrate RFS over a 56kbps TCP/IP WAN! ;-)
