Hi, it would be interesting to see whether it ran faster on IronPython which
compiles Python code to a .NET backend. Apparently the CLR backend can
actually speed up execution times too.

I banged away at my implementation for a few more hours last night. I
didn't hear anything back about errors, but I tweaked it for about 30%
speedup (i.e. still MANY times slower than the Altivec C version); and also
added some more documentation and a command-line execution capability with
options roughly matching the C hashcash module.
The permanent URL for the module will be:
http://www.gnosis.cx/download/gnosis/util/hashcash.py
I will also incorporate my hashcash.py into my Gnosis Utilities, which lives
at http://gnosis.cx/download/Gnosis_Utils-current.tar.gz. But that has not
happened yet; and there is certainly no requirement for someone who just
wants hashcash to use my whole package. In any case, the relative location
will be the same in the package as it is from the "live URL" for the module
(you'd just use 'from gnosis.util import hashcash' or the like if you
grabbed the whole package).
Anyway, the version I just uploaded is still roughly alpha... but let's call
it a pretty good alpha :-). I'm certainly more than happy to improve it
with suggestions.
Yours, David...
