Hi Dave,

That sounds like a great idea. Could you add that use-case to the Wiki 
with some detail on the input/output node re: echo-suppression?

Chris Rogers, I am wondering if the behavior Dave is speaking of 
(combined input-output node) is something you have had a chance to 
consider yet in your work on the Webkit spec?
