A few years ago, you folks provided a small teachpack to one of the 
TeachScheme! workshops that did TCP connect/send/receive. I used that to 
set my students a chat program exercise, where the chat was between two 
DrScheme interaction windows on different machines. Graphics in this 
case would be gilding the lily, as would running Eliza over the network 
instead of on one machine. Do we really have to tart things up in order 
to sell them to students? (I'm sorry if I'm being curmudgeonly. When I 
tell my students that Facebook Chat was written in Erlang, they perk up. 
But that doesn't mean I want them programming Facebook Chat in my 
course.) --PR
