The schedule for the D*C space and science track, headed up by our own jonnyx, is available for your perusal.

You'll also find at least 4 MemeStreams regulars presenting both here and in the Electronic Frontiers Forum. The schedule does not appear to be updated yet, but Decius and I are confirmed to be speaking at the Hacking 101, 201, and 301 panels.
