As described previously, multi-input mixing is handled transparently
by the engine. no client/plugin ever deals with this.

No, its so that applications that want to produce a UI that includes
list of real physical i/o stuff can do so.
h/w monitoring is not part of the client API. what you saw was more or
less the full extent of it.

yep. as described in the comment for audioengine_port_register(), if
the port type is not a builtin, then a buffer must be provided as the
4th argument. i should also have documented that PortIsMulti is
illegal for such ports (to ensure 1:1 connections at all times, for
reasons documented in previous discussions).
