The media check may or may not re-occur, this is the only area I am not sure about, any in any case all you are doing is loading the exe from the original, and then loading the content / data files from the copy, which is of course signed (or most likely the cache, which has been mentioned in earlier posts). You cannot boot a different game, if you understand the above. If you boot PGR3 exe, and then swap for Kong, it will give you a dirty disc error because the files it needs aren't on the disc. You cannot launch another XBE file, and if you could, it would invoke the media check again and fail because it's on a DVD-R. This HAS all been proven dozens of times.
So, to sum up, this IS a pointless excercise.
With the sliders58's test, you have your answer : the media check and the signature check do not occured again. Those checks are done one time and only one. The next check will occured when the 360 will reboot or when the DVD drive will be opened.
If that hotswap can gives this answer, I can't understand why you thinlk is useless. Now, do your own test and comme to gueux to share your results as we do.... I'm not sure to see anybody from Xbox-Scene into Gueux... Proves me I'm wrong....
