Michael Heilemann of Binary Bonsai has created a Google Calendar for the schedule of Reboot next month. He promises to keep it up to date and also invites others to help him do that. You can add it as a public calendar if you use GoogleCalendar itself, or import the iCal file into Outlook (updating seems to then be needed by hand, but if not I’m happy to hear about that in the comments) or keep track in your feedreader with the XML file. The program is still sketchy now, as it is still being fleshed out by the participants. (found at the Reboot wiki)
