Asked that in the channel for you:
Preacher/mIRC: "We followed their rules to the letter reguarding game modifications (rules they drew up after GC was released), and since they had no problem with GC, and we followed the same exact rules, I say we are free and clear."
As you can see everything is safe. Apparently rules were created for game modifications including star wars or other copyrighted content after the release of GC (which was probably the start of it), the team now follows the same rules and demands, so there shouldn't be any problems. If LA had the intention of seeing this mod shut down we (i guess) would've heard about that long ago. The team wouldn't stick time in a project with no future. 
It's just a go-ahead from LucasFiles and then the party will begin, heh. So no worries.
