Well, for anyone who is interested, I recently gave a talk about Plan 9 at a meeting of the Society of Software Engineers at RIT, and the slides and a video are up at http://sse.se.rit.edu/programs/tech-talks/plan-9
There's probably not much in there for people who are already using Plan 9, but if you know somebody who is interested in Plan 9 this *might* be useful. It is quite long (about 45 minutes)... I intended it to be shorter, so you can see toward the end I keep trying to bring back the slides after the demonstration but always get interrupted with a question. If there are gross technical errors, send me an email. Some of the questions caught me off guard so I may not have given perfect answers all the time. John Floren
