I think Track, MasterOut and AudioClip would be ideal. If you don't know how
to design the GUI to give access to plugins in AudioClips, I would
nevertheless recommend to add the internal infrastructure to AudioClips and
MasterOut now.

There are indeed effects where this makes sense (reverb for example). But in
that case the plugin should take care of mixing the wet and dry signal, not
the host app. (Btw. the same effect can be achieved using AUX sends, once
they are available ;-)) So my recommendation: Pipe the primary audio stream
through the plugins rather than a copy.

P.S.: Are you aware of the problem of "latency compensation"?
