Err, while it is true that hardware solutions can be very fast,
they aren't that fast. I assume that you meant a chip that
could CHECK a DES key per clock cycle. In fact, DES was
designed for hardware, and should fit a pipelined system very
easily.
I know of no logic technology that can reliably be clocked at
2Ghz.
The fabrication cost of a small processor is usually about $15
depending on the technology (Heck, Pentiums have a die cost of
around $50) if you don't count the initial masking and design.

Feel free to correct me however...I'm interested in seeing
literature about a 2Ghz clocked chip...
