Hi James,

I did something like this last Summer. In my case, I was using two Linux
machines, but the principle was the same. I found that I could only make
it work if the executables were in my home directory I didn't really have
time to find out why. Here's the essence of my shell script:

# script starts here
setenv CHESSDIR ~/testmatch

~/bin/xboard  -fcp "./ewith xboard" -scp "./gwithout xboard" -sh 99.99.99.99 \
        -size Middling -animateMoving False -mg 20 -sgf testmatch.pgn \
        -tc 5 -inc 2 -showCoords True \
        -popupExitMessage False

# script ends here

Notice that ewith and gwithout were both in my home directory on Linux
machines. Notice also that I had to specify the host for the second program
(-sh) with the ip number, rather than the domain name.

This worked fine and I played well over 1000 games like this.
