i'm familiar with the principle, they're quite fun and effective.
RIES does the same, and samba's DOS codepage to unicode algorithms
were found using monte-carlo testing as well.

my feeling is: an intitial assessment we might as well just use a
couple of brute-force searches on one or two crude parameters.  this
would tell us a great deal, in a very short timeframe.  if that gets
to over say 18% just with that it's worth refining.
