So you simply specify which machines have Zen installed.    In my
configuration file, assuming we use my tester you basically configure the
machine like this:

player = Zen-4k
desc = Zen at 4 playouts per move
invoke = ssh foobar.com /home/joe/bin/zen  -playouts 4000
level = 4000
Hash = 128

Of course this might look a lot different for Go,  and I have no idea how
zen is configured for level, etc.

At the top of the configuration file you specify cpus because the tester is
designed for multi-core and you might want to limit the number of
simulatanteous games to 4 on a quad core, etc.     But for this application
that is not so relevant,  so we would want to provide for a way to limit the
number of running instances of ANY program on the host machine.   For
instance we might not want to be running more than 4 programs at any given
time on the foobar.com machine.

I think it might be easier to manually set these matches up with twogmp or
something like that too.    That would be easy.
