(re: Swapping and the Weezer Idea) Yep, that sounds right. Somehow, though technically Sierra Entertainment could be considered “fan based” it’s more in the line of fans buy the programs, and then more derivative stuff is mass-produced, but don’t ever think of distributing their old stuff–ever!
Vivendi Universal has, where they’ve known about such swapping and trading in the open, leveled court orders against the people responsible. For more info about it from a source that has dealt with that exact problem, check out (if you haven’t already)
As I recall, they have an explanation of the mechanics of it all.
