Maybe Fergals point deals with this. But in any case, I still believe the
issue is over blown.
Even if someone had complete control over the random number generator,
it could not influence the outcome of the vast majority of elections.
Also, since it should be possible to know which (if any) election outcomes
could possibly be affected, this would allow close scrutiny
of these elections. It is interesting that it is at least possible
to do this with a computer. I have no idea how you would
investigate bias in the old mixing system.
