I think the pilot as a pilot was very well done. In terms of future similar meetings, I still wouldn't change much. Only that users/students should need to become sufficient users of the environment so that it is the topic itself that becomes the prime challenge and interest, rather than working out how to use the environment. But this easy to do, it just requires a greater time commitment to learn how to function well in Second Life (making notes, objects, using the inventory to find things, and learning how to give things/notes to others). Whereas Moodle, of course, requires no time at all for an average internet user to learn to navigate.
