[Nel] Something I don't understand about the license agreement.

Well, you summarised my summaries...

According to Sal:

There are probably a few minor code modifications, required to support
very specific rules (if you want to run elections, the code for booths
and all that is probably hard code). But, if we've done our design right,
most of a MMORPG design should be a matter of fiddling data.

Not "could". Is. It's automatic and non-debatable. When you write it,
it is automatically covered by copyright, and you have to explicitely
put it in the public domain (which is not *that* easy). With the
provision about plot; as I explained before, a plot cannot be
copyrighted, while specifics are. You can't copyright "evil arch-villain
wants to overthrow king", you can only copyright "Mezzo Kharkan wants
to overthrow king Ariflax".

(hmmm, if I have infringed some copyright here, it's purely unintentional,
 and was only for purpose of citation. Honest)

>     I think 'derivitive works' pertains to modifications of the Nel codebase

In the GPL text, yes. Derivative works refer to code. GPL says exactly
nothing about data, so it's not covered by the license.

That's a good example. However (assuming Everquest code was GPL), once
you'd produced a set of player and NPC models, and made a few zone files
under a 3D modeller, and created your own items, you'd be able
to launch Realquest.

And try to put them out of business :)

By FSF's own admission, the source of any library "not commonly available
with the system". Otherwise, we'd have to provide the Nvidia OpenGL driver
sources if we wanted to run our game on a Nvidia-equipped PC :)
