[vcf-midatlantic] Friday classes @ VCF East

I'm starting to plan the Friday tech talks for VCF East. Andy D. said he'll do one about TCP/IP for vintage Unix computers. That gave me an idea: what if we do a whole *nix track? There are five classes per track. Each class is one hour. So, please speak up if you'd like to be an instructor. (That's important. We need people to say, "I will do it," not just "Someone should do it.")
