Hi Frank,

I've had something like this working properly, but I'm afraid I can't find my
scripts. Over one summer, I played more than 1200 games this way. One thing I
remember is that I had both programs running in my home directory (ie
/home/andyw). For some reason, the one which was running remotely couldn't
change directory or something. This was all at my former employers' place. I'll
have a dig through some old CDs to see if I've got backups of the scripts
anywhere.
