Tor: an anonymizing overlay network for TCP
"Tor (second-generation Onion Routing) is a distributed overlay network that anonymizes TCP-based applications like web browsing, secure shell, and instant messaging. We have a deployed network of 30 nodes in the US and Europe, and the code is released unencumbered as free software. Tor's rendezvous point design enables location-hidden services -- users can run a standard webserver or other service without revealing its IP.
I'll give an overview of the Tor architecture, and talk about why you'd want to use it, what security it provides, and how user applications interface to it. I'll show a working Tor network, and invite the audience to connect to it and use it."
