Sorry I suppose I should have been more specific in what I was asking. 
I was looking for something like what Mr. Hinsen suggested.  Though, I
am also interested in RPC;  I didn't expect to get responces about
that.  Glad I did.

bye the way, the above links are a bit off. I believe they should be:
ftp://dirac.cnrs-orleans.fr/pub/ScientificPython/
and
ftp://dirac.cnrs-orleans.fr/pub/MMTK/

Thanks.
