This analysis seems to assume that the entire production run of a standard product is subverted. More likely,I think, an organization like the NSA might build a pin-compatible version of an existing, commonly-used product like a keyboard encoder chip that is designed to transmit (by RFI signals) the contents of what is typed at the keyboard. It's simple, it's hard to detect, and it gets what they want.

I thought that most (all?) chips already radiated on the electromagnetic spectrum? Isn't that what tempest is about?
