It would be nice to have two hash functions, optimized separately for 32-
and 64-bit processors. As the Skein report says, the algorithm can
be adapted to 32 bits easily enough.
I also did some work a while ago to adapt the Skein parameter search
code to develop a Skein-192 (6x32 bits) that would fit into registers
on x86-32. (It got stalled when I e-mailed Niels Ferguson about it
and never heard back; it fell off the to-do list while I was waiting.)
The intended target was IPv6 address hashing for sequence number
randomization, but it could be used for pool hashing, too.
