Regarding the existance of brute force machines.  The other player,
AFAIK, is jumping straight to ASIC.

One thing that has been missing from this discussion of prices are
engineering costs, chip glue, power cords, interfacing, etc., which
actually adds a great deal to the overall cost.

AccessData is building a massively parallel computer to break Word &
Excel documents (and DES for kicks) out of FPGA's and DSP's; the
estimates on the 40-bit RC4/MD5 authentication MS uses are 
~20,000 keys/sec/chip, with 64 chips per box, or ~1.3 million
keys/box/sec.  The boxes will cost $6-8K, depending on the chip and
quantities.

For DES, we'll only be at ~1.2 billion keys/box/sec; we're hoping that
once we have this proof-of-concept (i.e. the parallel processing boxes)
and all that overhead taken care of, someone will foot the bill for
developing the ASIC chip (1000% faster, at least) and we can
plug-'n-play:-)
