The call for papers for TechWave 2008 is now open. Initial applicatons must be submitted by March 18th. Final presentations have to be submitted by June 25th. TechWave 2008 is August 4th through 8th.
If your paper is accepted, you can attend TechWave for "free". I know that included the pass to TechWave itself. I don't know if Sybase covers travel or hotel costs.
