It should be possible to drop in a coprocessor board to handle the encrypt/decrypt. It's compute bound rather than bus bound so it should speed up nicely.

Most of us throw that in the form of an HTTPS-stripping proxy on a Pi :)

I mean, that would be the sensible approach. I was just thinking that designing an FPGA board for my Apple II might be...fun.

It does sound fun, although I shudder at trying to prove that such a thing would be free of side channel attacks.
