Just got back from Usenix 2003. The paper glyph and I wrote is available: Networking For The Rest Of Us, as are the slides. I'm still not sure we got the point across well, but the points I realized I wanted to add (configuration as scripting, ability to encode common configurations in a deployment generator, unified authentication backends) wouldn't have fit in a 30 minute talk anyway. Some of this arose from the time Glyph spent presenting Twisted to various sysadmins, and our plans to reimplement the authentication infrastructure.
The conference itself, while small, was extremely interesting and educational.
