      It's amusing to hear this from someone in the UCLA computer
science department.  See Popek and Walker, "The LOCUS Distributed
Operating System" (ISBN 0-262-16102-8), which describes a system which
among many other things offers exactly the facilities Tamir wants,
and is, according to the book, running at the UCLA Computer Science
Department on a large scale (a figure of a half million connect hours
is mentioned, spread across a large number of machines of different types.)
Locus supposedly supports reliable, distributed, redundant files, transparent
load-sharing, transparent inter-machine forking, transparent execution of
programs on remote machines of a different CPU architecture.

      Whatever happened to LOCUS, anyway?
