I wouldn't recommend installing a MOD chip on a 360 just yet. AFAIK, the 360 is the first console that fully embraces the TPM (Trusted Platform Module) "stuff". Basically, each xbox has a unique ID number. That number can be traced to whoever bought the unit unless it was paid for in cash in a place without security cams. If they cracked the TPM, my hat goes off to them. If they didn't, read your
EULA manual very carefully... page 24... at the bottom:
"Caution:
Any changes or modifications not expressly approved by Microsoft could void the user's
authority to operate the equipment."Notice the wording; "authority". Can they remotely "shut off" your 360?

Unless the TPM is disabled, they know exactly which box it is AND who bought it. And if the TPM *is* disabled... you just might be a terrorist.
I remember the cable company knocking on the door of an old girlfriends house. They wanted to know if they were going to start paying for the cable they were pirating. That was like 10 years ago. Last week I was talking with a tech at the cable company trying to troubleshoot my internet connection. It's Orwellian what info they have about what's inside your house. He was able to help me repair a router I had that was behind
another router.
It's 1984, be mindful of what you do.

The PC you're on probably has some kind of TPM as well. Dell, HP & Gateway have had TPM for awhile now. Look through the literature for your mobo and see if you see anything about TPM, Presidio, Palladium, or Lagrande. I'm not deep enough into it to know the ins/outs of each system or when each was introduced, but I *DO* know it was pushed by the DRM guys for about 8 years now & the Dept of Homeland Security gave it the final push. Somebody somewhere is logging everywhere you go and what you do when you're there.
