"Pretty much sounds like a no-cd crack" When it has nothing to do with removing cd key checks other than its not even the same game engine anymore so that license does not apply. I don't really want to keep discussing this, so: A) The license agreement with the game will apply to assets (Nothing from the assets will be distributed with iojamp if it ever released) B) The SDK License agreement prevents you from making new mods that don't specifically also run with jamp. If you keep them compatible, then I don't see it violating this (the same applies to Quake3 mods that are still closed on the MOD SDK) C) The iojamp license is under GPL rules, not the license agreement for the jedi academy installation therefore the cd-check bits do not apply.
