This year's largest underground Inernet security gahering on the planet is being held in Las Vegas as I'm writing this here. The admission was $75 cash [no cr3dit c@rd], seems hackers do not trust each other anymore! DEF CON phreaks envision the perfect world as:

"Computer networks would welcome curious exploration, all information would be openly shared, a lot of public toilets would be filled with concrete and no swimming pool would go unfilled with several blocks of dry ice."

There is a 802.11b wireless network this year; so everybody can use the Internet, check out their own servers and mess around with other's servers. There's also a ftp/web server to be used as a file repository for the people who want to share their photos they have taken at DEF CON and save the bandwidth of the net connection.
Everything seems to be peaceful this year at DEF COM. Last year, it was ended with the arrest of Russian programmer who gave a talk on electronic book security and programmed a software to remove the user restrictions on encrypted Adobe e-books.

Speaking of network security and hacking, let me tell you about this web site! It is pretty scary and thought that you should know about it... Now you can see anyone's drivers license on the Internet, including your own. I just searched for mine & there it was, picture & all. Check this out. It's a great invasion of one's privacy.
