Let's look into a little example. One of the operations a control
interface would allow is to originate the generation of another channel. 

How exactly would you allow a useful but limited channel origination
action? What exactly is "limited"?

Suppose I want I user to be able to originate calls from his phone. I do
want to allow Joe to originate calls from SIP/Joe (or is it ZAP/12 ?).
I don't want Jow to be able to originate calls from SIP/trunk/123456 .

I want to be able to let some remote users connect through those
interfaces. And we can't really trust remote users to play nice.

How do you link such a remote user to some limitation on channels?
