My talks at Microsoft TechEd in Dallas will be:

WEB404: ASP.NET Web Services Extensibility: "I didn't know you could do that!"
DEV359: Aspect Oriented Programming
DEV357: Building Distributed .NET Applications

The last one (which is likely going to be rescheduled to earlier in the week than Thursday) is the most important and ambitious one. I will try to give some guidance around the "appropriate use" of .NET Remoting, Enterprise Services and Web Services and show that there that there's no "vs." or "or" between those three technologies but an "and". I'll talk about layers and tiers, process models, security, data, objects, services -- all in a bit more than an hour.
