For those attending WWDC, and wanting to have the module complete schedule in iCal (as suggested by TUAW), I’ve created a small script (using Prototype) that will transform the JSON data of the official WWDC schedule into calendar files, which you can save and load into iCal.
Enjoy! I hope this will be useful to you. By the way, if you’re attending WWDC, just leave a comment below.
Update, 2008-05-26: Thanks to Jeff LaMarche for posting a link to the calendars from the cocoadev mailing list, and to Second Gear for using the calendars with their own products! :)
