Acting locally

I’m here at Etech and I’m experimenting with an event-oriented weblog. Participants at the conference using the WiFi network who visit www.kottke.org/index.html will get a special Etech page. The Etech page has quick conference links at the top, my current status so that people can find me if they wish, a little more space in the sidebar for the remaindered links, as well as some aesthetic tweaks. Folks not at the conference will still get the normal front page and can view the Etech page here. Now, how do I encorporate Confab into the mix?
