I still don't see how all this OS stuff got into the discussion. GTP
never talks about pipes, it only needs a communication stream such that
the controller can send text to the engine and vice versa. Whether you
do that by listening to a port, or via a serial line, or via a pipe, is
not specified in the protocol.

Of course, in the setups in which we are using gnugo, it has always been
pipes (either from a GUI that forks off gnugo, or from a regression
script, of from one of our twogtp scripts).

In a tournament, the most likely setup seems to be using 3 computers,
with a controller running on a machine provided by the tournament
organizers, the engines opening up a port on their computer, and the
controller connecting to them via TCP/IP. If you really prefer the
serial line then this should work, too :)

Noone has ever suggested that.
