Actually, Ray used GUSI for a while, but that was in its first 
incarnation - on top of MacTCP, IIRC - and going through the Tcl layer, 
through the GUSI layer, to the flakey Mac layer, was very unstable, so 
he hand-rolled the current code on top of MacTCP.

Yeah, I looked at this a while ago, and I decided I didn't have the time 
for it either.  My guess is it would probably be just as easy to rewrite 
the MacTCP code using OT, but I can't say for sure.

Yes, this would be great.  It is also a pretty fun little lab for 
someone who wants to play around with socket programming a bit.
