Have you checked the JDC 2010 agenda, if not yet you can see it here.
Jspx has been enrolled to run starting from 12:30 to 1:00. only for 30 minutes right after the first coffee break..
also on the second track, Ahmed Hashim will be conducting a parallel session.
Well, it is a bit of challenge, to conduct the jspx fully in 30 minutes. But we are working on that.
I hope to allocate time to work on the presentation for the event.
