Aahh... But there is a slight problem -- wouldn't the viral effect of the
GPL come into play here and prevent me from doing so? (referring to the
clause that states all derivations of the product under the GPL must be
under the GPL)

How so? I would figure that having a direct clause like, "if you use this
software for monetary gain" would be discriminatory enough to do this job.
Where else would you sell the product for "monetary gain" except in a
commercial enterprise?

Ahh... Non portability of code to another application is a slight issue, but
that wasn't the kind of development I was thinking of. Ex: Quake came out
for DOS. It wasn't until id released the source that it took off for us
"alternative operating system" guys. In the process, id neglected an entire=
ly
untapped marketshare. This is not unforseen, as the company was fairly small
and didn't have the massive army of coders required to keep multiple ports
of the game maintained, etc. Quite frankly, I'm surprised they managed to do
so well with the game, even though they had to port it from NeXTStep's
Objective C to raw C (could be wrong here -- had a chance to ogle at the
source a while back, and I can't clearly remember which language it was in
in it's final form).
The idea with the open-source engine is the ability to leverage the
developers out there that are interested in porting the game to their
platform, and allow us to reach that marketshare that id and virtually every
other game/applications developer has neglected because of development
costs. Since we'd be selling the datafiles primarily, we still make
money, and we tap that untapped marketshare all in the same strike.

Hrm... From what I understood as the mission of the open source/free
software movement was not to make the software "free" as in beer, but "free"
as in distributable and hackable. As such, if the engine were to be licensed
under such a license, wouldn't this follow the same principal?
The idea of commercializing the open-source engine to other commercial
developers was something I tacked on to the original idea at the last minute
-- the original e-mail was written up just before I headed out to class, so
it was a bit of a jumble. =3Dop
