Actually, I've written a script in Python that does just that for a
Scyld system, crude job migration.  It just rforks() to the remote node
then does an exec() of the binary on that node (after twiddling with
stdin/stdout some).  This assumes that the program you want to run is on
the remote node as well as any libraries it needs (I assumed the binary
was on an nfs share, and that the libraries were already cached on the
remote node).  Of course to do this, you need BProc bindings for
whatever scripting language you're using.  So far I've seen bindings for
Perl and Python released.
