Carch: I'm pretty sure this means that there may not be supportfor people who try to create custom monsters, or tilesets (suchas a desert tileset) that don't ship with the game. In terms ofhow players will use modules created with the toolset, i.e.whether you auto download when you connect to a server orwhether you have to dl first, install, then connect, I don'tknow. I'd guess it's going to be more like Myth, where you dl,install, then play.
Ultimately, I'm guessing they will provide some manner ofsupport for people who create custom content outside of thetoolset. Still, who knows?
