Imagine, you have a switch.... you use this switch for original (Xbox Live) and on the other hand: custom firmware: for your own good! Xecuter is absolutely going to release the package, which I like a lot. Just plug your drive in your pc, wait a few secs.... and you ready to play back-ups... that would be fucking awesome!
However, Xbox LIVE is going to be a problem if you think about it... Updating the 360 will be a pain in the ass.... maybe they include a nice DVD firmware flash including a nice protection on the firmware so you can't fuck with m$ again.... that would suck!
I don't like this PSP style of updating.... however I have to live with it!
