anyone with a littl eknowledge in any type of program shoudl quickly grasp the concept of a media check, and understand that loading one executable from another executable isnt going to alter the code of the second executable in any way
bunnie undercover? dont make me laugh, but if for some reason bunnie decides to be a dipshit like this, well then we will just hack 360 without him

Although I understand the concept of the media check, and accept that the 360 demo disc piracy thing is a load of crap, we really don't know chain of execution.

Allow me to play the other side for a minute. I believe it was said somewhere that the Xbox 360 is capable of multitasking in that it can run (at least) two .xex files at the same time. We, however, currently lack an understanding of the method by which this is done...is it done as a fork() style command? Does the hypervisor create another virtual machine to run it under? Some odd option number three? We simply don't know yet. *IF* it is fork style, and *IF* MS coded it poorly, and chose to pass down signature validity and media check the child processes (which *could* be the case...if multiple .xex files are packaged within a single release, it is conceivable [though not likely] that they could do this, to minimize the need to get each .xex signed for the single release), then there's a glimmer of hope. Now, this is a very long shot, I'll admit it. MS had many eyes going over the development of the 360. But let's not forget that the "most secure version of Windows ever" (Server 2003) was rooted by RPC DCOM only a few weeks after being rolled out.

That being said, I personally don't believe that the demo does fork in such a way. It would be a large mistake on the part of MS. Not that they've never made a mistake or anything...that'd just be quite a large one to make.
