Basicly what it seems to boils down to is that alot of code was released
before SCO bought Caldera, Unix. or the exclusive rights (If they indeed have them) so being as this code was already released under GPL prior to their acquisition they're screwed. What's done is done.
You can't give away something in the public domian then turn around and say, oh we've changed our minds now you've got to pay us to use it.
This whole deal is out of a temper tantrum. IBM pulled out of their little deal thus taking away the engine for their gravy train so now they've got to do something to look good. They've bitten off more than they can chew now they are choking. Eventually they'll turn blue and fade away.
It's just funny how in this case the
Big Blue has them by the short hairs.

It's abvious all who turn blue arent going away anytime soon! lol
