Albeit I may pay for it later, this is a great place where TPM (Trusted Computing) could be used. Within the TPM system, the chip responsible for key management is the only one that can ever "see" the keys being used.

Any time a key goes out, it's encrypted. So, you can send in an encrypted key, a datastream, and an encrypt/decrypt/sign/verify instruction... the chip does the magic required, and spits out whichever data was asked for.

Note: While Palladium is evil. I actually like TPM. (My ThinkPad has it, but I havn't had the opportunity to set it up yet).

To make a desparate attempt for on-topic-ness: I disliked HTT from the beginning. It didn't seem worth paying for... It makes more sense (to me) to fine-tune cache performance.
