Having reread pages 78-81, I guess pagers, usenet, and slow email are pretty much out. I looks like I am going to have to track down the proceedings from Crypto 85, 86, and 87. (Still in print? Expensive??) All the main sources seem to be in them. Though all the applicable literature talks of playing poker, it seems more general and politically wiser to talk about playing cards. Besides, "PPP" is already in big-time circulation meaning "Point-to-Point Protocol", "PP" for "Poker Protocol" is only two letters--of course verboten. "PGP" for "Pretty Good Poker" would only get Phil's lawyers after me. That leaves "CPP", for a nice wholesome card game. -kb, the Kent who might actually do it -- Kent Borg +1 (617) 776-6899 kentborg@world.std.com kentborg@aol.com Proud to claim 32:00 hours of TV viewing so far in 1994!
