We already had one developer try it out and get confused because the server 
tried to treat the callback URL as a JSONP callback.

The protected resource typically accepts "callback" as a parameter to support 
JSONP. If a developer accidentally passes in callback there (maybe they got 
confused) then the server can't give a normal error message - instead it needs 
to either detect that it looks like a URL or otherwise reject it.

On a related note, I think it's more confusing calling it something different 
in the user-agent flow (redirector) when it's essentially doing the same thing.

I don't think it is that confusing. Its a completely different context from 
where JSON-P is used (note that in the User-Agent flow it is called something 
else).

With the simplified params, the callback url parameter is now just "callback". 
Since most major API providers already use "callback" to signify JSON-P 
callback, can we rename this to "callback_uri"? This will help avoid collisions 
and confusion.
