Joe,

I disagree with your suggestion "The software performance of security protocols has been the more substantial issue, and is likely to continue to be for the forseeable future."

I suspect that most desktop users do not need hardware crypto for performance. Irarely if ever drive my GiGE interface at its line rate. With fast processors, especially multi-core processors, we have enough cycles to do symmetric crypto at data rates consistent with most application demands for individual users. Public key operations for key management are usually low duty cycle, so they too can be accommodated.

Steve
