That's all very true. Another complication of real-world classes is... buying the educational licenses for Maya, renting the space involved, buying/renting projection equipment, computers.... One possibility is to do some kind of partnership with a school (or even with Alias) who provide the equipment and classrooms. Here in Austin, about a year ago or so, conceptart.org had a big "expo" kinda thing, where they had their bigwigs each presenting courses and so on. I think the entry cost was something like $400-500 US, not including plane ticket costs, hotel, transportation, etc. They managed to get a couple hundred people all crowded into this relatively small space. It was freaking HOT in there. lol But that kind of thing IS possible, given the public's interest is high enough.
