NAP building

Hi, I was tossing the idea around of building a local IXP in the San Diego metropolitan area. But I have a lot of dumb questions to ask. I'd like to talk to someone who has built an IXP. If you would respond by private e-mail, I'd appreciate it. Thanks for the help. I'll summarize if there is enough interest. Tung-Hui Hu hhui@arcfour.com
