HEY! I've read Schneier (if that is what you meant).
Eric also went into various details of how to reveal cards to
individuals (my hand) and all players (the current trick),
etc.--details I am not prepared to comment on yet. I have some
reading to do first!
I also need to review (learn) a collection of card games to appreciate
their requirements, whether there is a tractable common set of
operations. (Ironic to have a virtual non-card player consider this
choice of project.) Crypto is not the only thing I need to read.

No. Schneier is a start, but the source papers are really a must read
for an actual implementer.
Schneier's book is very good as a survey of technique and ideas. The
bibliography is _excellent_, and make the survey truly useful.

I remember my crypto professor going over this as part of the last week of our
crypto class. Somehow, there was a snag using RSA, and if I remember correctly
he used a model where both sides share the same N value. He ran across some
P and Q prime values where this didn't work, but with a shared modulus for
both players, it did work.
Bruce Schneier's book didn't mention this snag, so either that was an error,
or there's something else we overlooked durring the simulation. (This was a
blackboard simulation, not a computer simulation, but it failed with some
small numners... :-)
Anyway, you can ask him about it, his address is rvslyke@prism.poly.edu
