I've submitted a pre-print of my anonymous credential system to the IACR
ePrint server.  Thanks to all of you who responded to the questions I posted
here while working on it.  I'd love to hear feedback from any and all before I
sumbit it for publication; particularly, I want to make sure I haven't
forgotten to give proper attribution for any previous work.

It mentions how to use the blinding technique Ben Laurie describes in his
Lucre paper, which I don't think has been mentioned in the formal literature,
and also describes what I call a non-interactive cut and choose protocol which
is new AFAICT.  Thanks again!
