content: I'm not very experienced in processor architecture, just some embedded programming, but this thing seems to have read/write access to the rest of the processor's memory, which would allow it to see everything your computer is doing and alter it. The lack of transparency means that you have no idea what it's doing, or even if it's been compromised by someone other than intel and the firewall bypassing server thing means that you have no control over what information it sends/receives.
