FYI, there's a two-day event happening (unrelated to the PLATO@50 conference happening June 2-3) on April 15-16, 2010 at the University of Illinois's Alice Campbell Alumni Center, in Urbana, Illinois. It's called "Fifty Years of Public Computing at the University of Illinois."

I mention it because one of the projects being celebrated is PLATO, and Don Bitzer is expected to be on hand to give a talk about the system. Other projects being covered include Project Gutenberg, Mosaic, and PrairieNet.
