What do you mean by streams, in the context of PHP? Or do you just mean as a
design element.

That sounds fine, and like it'll integrate well into how rpc.php and the
Horde_RPC framework work - there's just selection of the backend based on the
content-type, and then calls a general process method.

Let me know if you have dev questions.
