The PDC site doesn't have a great search tool for looking at the sessions, and if you want to print out all the sessions to plan what to attend you'll have to print ~21 individual pages which is awkward.

But the nice guys organising the PDC have offered a RSS feed, so internally I've knocked (and hacked) up a simple ASP.NET site to consume this feed and slice/dice the data in all the ways you could possibly want, even implementing some code to Import interesting Sessions into Outlook, RSS rocks :-)
