Concerns About Intel Sandy Bridge Anti-Theft 3.0

Is anyone else concerned about the the Anti-Theft 3.0 security features that are going to be included in the upcoming Sandy Bridge architecture? From what I've read, this technology could allow for bricking a laptop via 3G even if it is powered off or the hard drive is replaced.
This is scary for a number of different reasons.
Does anyone know if it is going to be included in all of the upcoming mobile chips or if it will be optional?

I won't be buying any laptop that has Anti-Theft 3.0 included.
