JavaOne 08 MEP Slides Available
The JavaOne 2008 MEP slides provide a very good technical overview of the platform and its many features - Take a look! Unfortunately, the session wasn't recorded, so there's no audio or video to accompany the slides.
The presentation covers the platform's features and overall architecture including the client and connector programming models, security model, provisioning, and much more. During the presentation, we had a live demo on stage of a secure client (running on a BlackBerry 8830 and a Palm Treo 700P) that performed synchronizations through our mobile carrier's network, over the internet, and through Sun's firewall to a MySQL database running in Colorado.
