Some hacker convention. It doesn't have anything to do with crypto per se.

Here are just two of the topics which will be discussed: Bruce Schneier, Author of "Applied Cryptography". TOPIC: Will speak on issues surrounding cryptography, digital authentication, digital cash. EFF. TOPIC: Will cover current legal threats, privacy and computer information networks. I believe last year's key speak was Mr. Phil Zimmerman. There are currently 22 speakers registered for this year's convention. :) See ya in Vegas.
