I put together an iCal calendar for the Pd Conference, I'll try to keep it up to date as well. Anyone using Mozilla or Apple iCal can subscribe to it and automatically get any updates. Outlook users can import the data.
Here's the URL:
webcal://dropbox.at.or.at/dropbox/ical/hcs/Pd32Convention.ics
If anyone has a burning desire to maintain this, I would happily hand it over to them.
