Plus, since moonlight is technically language agnostic, those who want 
to write in c# could, those who like c or c++ could.. With IronPython or 
IronRuby or even Javascript there are a number of options for scripting 
and having user interfaces that work seamlessly together.. Regardless of 
the technology used to build the application code underneath.  From my 
understanding.. We could even mix with different UI elements interacting 
with different types of applications ... By that I mean portions of the 
same UI could be sending events to scripts or C# or c/c++ code. Is that 

And XAML can be created dynamically giving the ability to not just 
theme/skin but completely alter the UI at runtime.  By that I mean you 
don't have to have a static interface with a skin file and theme but the 
interface could be radically changed as new code is added and new xaml 
nodes are created.. Does that make any sense?
