The main Informix related topics can be viewed here: Data Servers - Informix, also scheduled are some pre-conference technical education courses on Sunday 14th, including a one day Informix Dynamic Server Problem Determination Class. I'm scheduled to talk about "Rapid Development using Java Server Pages (JSP) and IDS" on the Wednesday, though I hope I get to attend the rest of the conference. Entertainment will be provided by Wayne Brady and Gladys Knight! among others.
Here's a link to the conference blogs.
