Application Designer and Web Application Projects and Biztalk

I'm working on a project now that has a lot of components and web services and a few client applications. And Biztalk.

I'm using Application Designer from Visual Studio 2005 Team Architect edition to model the components of the system. While the model has been quite useful to help me flesh out the project names and interfaces and such, there are a few "wishes" I would like to have to make it a little more useful:

• it would be nice if you could model class libraries in there somewhere, because our web services in particular have very little logic in them, rather the logic is in the class libraries.
• it would be nicer if you could use the new (beta) Web Application Project as an application type in the model - I prefer this project type especially when the web service project is a pass-through mechanism for the functional class library.
• it would be nicest if the Biztalk web service model shape would let me model a Biztalk web service. I know, I know, that sounds stupid, but I expected to be able to model an as-yet-non-existent Biztalk web service in my system, but what the shape wants is the WSDL for an existing Biztalk web service.
