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
