Having a "Stream" interface equivalent to the FileData interface, with a 
"URL" attribute that gives you a URL that returns that stream, is the way 
to go, IMHO. This would give us the broadest options for integration with, 
e.g., WebSockets later (we could just add an API that takes a stream, and 
another that returns a stream, for instance). Having consistency across 
all the various APIs in this manner is strongly desireable, IMHO.
