Silverlight doesn't support ICustomTypeDescriptor, which is how IronPython objects interact with data binding on the desktop. For a workaround, see http://devhawk.net/2009/04/24/clrtype+Metaclasses+Demo+Silverlight+Databinding.aspx
I believe Silverlight 4 supports IDynamicMetaObjectProvider for data binding, so the need for emitting your own CLR type goes away with that release.
