This is grand fun.  I will be in Toronto.  This party is in Portola
Valley.  It's not really near mass transit, but perhaps people can car
pool (or form an alternative party nearby transit).

> A party to celebrate the expiration of the Blind Signature patent. 
> WHY: 
> U.S. Patent 4,759,063 ("Blind Signature Systems") to David Chaum is 
> the core

> WHO: 
> If you know what blind signatures are you are invited.
