Cool...can't wait to hear more, I'm gonna brainstorm w/ a software developer friend of mine...maybe we can come up with something to help, he's familiar with protection schemes like that. We worked on a little program for a while where I used to work, the program's different features called the class ids of files instead of the filenames themselves...I dunno if that would help, but I will ask to see if he has any tricks up his sleeves, if thats even along the same lines as what you guys are doing, you guys rule...you all will nail sc2 sooner than later, take it easy.
