On SigAda 2002 a paper was presented for a Satellite Terminal
Simulator called TSim. They used gnat, Tcl/Tk, TASH, AdaSockets and
the Booch Components and in the paper they state the following:

"Throughout Round-3, we managed to retain the source code
compatibility between Win32 and Linux. So, we could also build
distributed TSim under Linux, and operate exactly the same way.
Miraculously, we also found that the Satellite partitions were
interoperable under Win32 and Linux.
That is, we could run the Satellite partition under Linux, and the
Terminal partition under Win32, with TC connected on the same or a
different machine. Or, we could run the Satellite partition on Win32,
and the Terminal partition under Linux, connected to TC on Win32 -
possibly the same machine running the Satellite server. This was truly
unexpected, and gave us something technically satisfying."

Well, they used the Distributed Systems Annex, but I'd guess, even
without that your chances are very good.

If all else fails, you still can add representation clauses to the
types you are exchanging to make sure they are represented the same
way on all target systems.
