Games like a Grrl Wrote:Actually, its a great move by Microsoft, one that any one of you would have done in their place.  But, does this cover the theory of doing this, or the specific method of doing so?  I've always been a bit shaky on mah understanding of patent law, but does this mean that, should Sony find a way of doing this completely unrelated to the way the 360 does it, they would still be barred from using it?

well i can think of a few games on the psp that you can use custom track so i don't see why not.... if they develop their own way of doing it by lets say using a proprietry file format then mirosoft shouldnt be able to do much about it....  but im no laywer
