Lotusphere 2008 - DXL Sessions?

Last year I had a great time with the DXL JumpStart. I've been thinking of what to do in oh-eight on this extensible topic and have been kicking ideas with other DXL presenters. Now that the Call for Abstracts is out, it's time to get serious.

Hoping to present relevant content that will help you in your application development, I'd like to know what DXL topics you'd like to see covered?
My favorite idea right now centers on great transformations, what's yours?
