I remain very skeptical about this annoucement. Nothing is free and the uncertainity involved (too many details unannounced) makes me cautious. This announcement was timed at the beginning of a concert industry trade show. Ozzfest has announced a new business model and it will generate a lot of buzz in front of the right people. Kids and the metal have-nots will be excited at the 'free' part. Personally, I'd rather pay for my normal seat/location/experience (PLARS). I like the value I've received the last three years and would buy it again in a heartbeat.
Jaco died for our sins so that modern bass players could be free to play more and be heard.
