So, how will the API accomplish things like logging an agent into a queue,
or redirecting to voicemail, or more exotic things like running an Echo
test, or playing a telezapper tone? Or asked another way, which use cases
aren't in scope of this API?

One frustation I've had in the past, is realizing whatever it is I'm trying
to do, I need to use another interface to accomplish it. Most commonly, I'm
writing an AGI script, and find myself needing to do something only the AMI
can do. But I've seen other odd combinations too, e.g. I've seen people
resort to using System(asterisk -rx 'some command') from the dialplan.

But it sounds like you're going to be exposing the Stasis-core API to the
manager, so at least I should never have to connect to both the AMI and
Stasis to do something.

On the subject of uniqueids and channel masquerades, I can point you to my
own email from a few years ago:
