Well, we don't have registration going yet, but the schedule has been finalised. In addition to the stuff on the Web site (<URL:http://ApacheCon.Com/>), there's an #apachecon channel at IRC.OpenProjects.Net and an open discussion list (send an empty message to discuss-subscribe@ApacheCon.Com). The IRC channel has an infobot, faqtoid, which will answer questions about ApacheCon and the schedule in particular. Try 'faqtoid: sessions about xml?' or 'faqtoid: sessions by schlossnagle?'.
Watch out, CPAN! :-)
Woo-hoo! Got my CPAN account a couple of days ago. Now, what were those modules I wanted to submit..?
