Dear Stuart
I just watched your video, it’s really great. I wanted to ask that if it is possible to have the designer hosted in my application instead of having it hosted in "Experimental Copy of Visual Studio" as you referred to it in your video. I basically want the business user to be able to use DSL  Designer(the one that appeared by pressing F5) from within my application at runtime. And would you please guide me as to what extent the WF are able to support the concept of DSL, after all what we do there is also to build a Domain Specific Language (Correct me if I am wrong).
