There's a class called XamlReader that can parse XAML and create the object
(form, control, etc) that it describes.  Once you have that object, you
could connect event handlers to it's events that forward the events back to
a server.  You'd have to know in advance which events to hook, I think,
since there will be literally hundreds of possible events from a form of any
complexity.

On the server side, I'm not aware of a XamlWriter class, but then I don't
have access to the docs right now (they're on a different machine).  In any
case, you can always build an XmlDocument with the approrpiate XAML code and
then serialize it to a string for transmissions to the remote client.
