If you have SOME utility that can be used from the shell to invoke
commands on remote systems, e.g. "rexec" or "remsh", then you can use
that as a basis for initiating the remote process, after which you
can exchange data on the stdin/stdout of the remote process.  The
main drawback to this is that most implementations of "remsh" and the
remote shell daemon are horribly inefficient, context-switching
several times per transmitted byte.  There are also a lot of details
to take care of, such as methods of binary data interchange between
heterogeneous systems.

For BRL's MUVES project I developed a package of code specifically for
this kind of use, the "Dx" package, and I've mailed you a shell archive
of that that I happened to have sitting around.  It will probably
require a modest amount of effort to port outside the MUVES context,
but it serves as a useful starting place.
