Or perhaps a modified 360 dvd drive that is connected to a computer and is then translated though some means physically to the main board sata port that the optical 360 device uses.. A combination of hard ware and software, could it be done?
from IntestineMan
"plug sata from PC mainboard to xbox 360 mainboard."
Correct me if im wrong, but wouldn't the sata cable need some hardware device *1, chip-set in order for it to translate the two sata host chip-sets from each other? a Big IF you could run unsigned code from the emulated drive. just doesn't pan out if you ask me.. or make sense...

P.S. Anyway i like the thought of having a pass though access from the original client device SATA chip-set xbox 360 drive to another. For instance similar to what your suggesting but a drive with access for online-LIVE dvd's and another drive for access to backups and such iso images for the PC.
