Don Box: XAML is just an XML-based way to wire up CLR types no more no less...  XAML is domain-neutral, so while it may be used to create desktop apps, web pages, and printable documents, it could also be used to create CRM apps, blogging backends, or highly concurrent web services provided you had a supporting CLR-based library to do the heavy lifting.

I guess that clears that up.
