Isn't the TPM considered such a device? There is no hope whatsoever of a solution for many, many, many years. Perhaps by then, or in the meantime something will replace the computer. I believe semantically we are saying/concluding the same thing. However, once again you read and interpret my post incompletely and out of context; and respond to it accordingly. If you require further clarification from my original post or this one, I do not believe I can restate any of it any clearer. No disrespect.
