This is very cool - I had a look the other day. Was wondering why some  
sources could be attached and some can't....
Best browser experience yet by far I'd say.

No problems about adding CORS support - for the record I'm very happy  
to implement new capabilities testing and other suggestions to the  
registry from anyone who cares to drop me a line. Especially if it's  
going to enhance and promote the use of the registry :)
