It's the tools that come from id. id's bsp compiling tools, if you use those
to compile the level then you are using id's tool just like
if you used 3dstudio to make a .3ds you have to purchase
the program. In id's case you would have to purchase a
licsense for the engine.
I remember a Level pack that was not authorized by id. It
was sold in EB and id wasn't getting anything from it. You
still needed quake to run the levels but id didn't get
anything from the sale of those levels so the lawyers went
after the people who made the pack. I think that's where
all of it started.
