An EMBASSY-like CPU security co-processor would have seriously blown the part cost design constraint on the TPM by an order of magnitude or two.
Compared to the cost of rewriting Windows to have a infrastructure that can support real security? Maybe, but I'm inclined to doubt it, especially since most of the functions that an off-CPU security co-processor can successfully perform are low enough performance that they could be done on a PCI or PCMCIA card, without requiring motherboard space.
Upon re-reading the paragraph I wrote, I can see how the text might have been ambiguous. I was trying to express that there was a cost constraint on the part. Adding the cost of an EMBASSY or SEE environment to the purchase of every new PC is more than the market for bare-bones or even mid-range PC's will bear. --Lucky
