I could but I want avoid that in this case...why?  This is for an example of how to do it for my students, so i'd rather wait for 1.1 to support this correctly than hack it together...it'd be interesting to get working but using URL re-writing (or my other issue with it in that I have to hack together the XAML to do it).  I'd like a better solution for it from MS as this is going to be a pretty standard use-case (taking a Silverlight control and wrapping it in an AJAX control. 

 This use-case works fine in 1.0 just 1.1 is lacking and I suspect they'll handle it in the beta.  I've posted this as a bug in that forum...but thanks for all the ideas!
