computer-go: Interfacing 2 engines for automated play

["Fant, Chris" <chris.fant@xxxxxxxxxx>]

I have decided to try my hand at some go programming.  It will be mostly
learning based so it will need to play many games against other engines.
What is the best way to do this given that I won't have access to the source
code of other engines.  It seems an ideal solution would be a program that
supports the go modem protocol via stdin/stdout and acts as a referee as
well as a graphical client for watching games.  Is there anything like this
available?  Any comments are greatly appreciated.
