This is interesting.  I wrote a small client/server system for the purpose
of programmatically executing programs within UML.  It works nicely, with
the exception that it is necessary to install the server within UML in order
for it to work.  It would be nice to be able to do this with a pristine UML.

What do you do with stdin, stdout and stderr?  I connect them to a UML
serial device, which can be connected to the tty (for interactive programs)
or any other UML channel.

I don't think this is particularly crucial; does it cause some unexpected
difficulty?
