I think you've hit on something there.
On physical consoles, the concept that corresponds closest to
plugins is an "insert".  Inserts may be pre-fader or post-fader
but AFAIK are pre-panning.  If the mixer strip is for a mono channel, 
AFAIK the insert is *always* 1-in/1-out. Nothing else makes any sense.

Likewise for stereo channels, the only plugins that make sense are

I'm now wondering if all this do-what-i-mean architecture/code isn't
biting off a bit much.  Maybe we should reduce the feature set here
rather than enlarge it. Define some simple constraints,
raise an error dialog if the user attempts to violate them,
and rely on busses and/or external JACK apps for anything more

I personally would prefer a rock-solid Ardour 1.0 with a simple
plugin system Real Soon, to ardour 1.0 with a really complex DWIM
plugin routing system later. This could always be revisited for
1.2 or 2.0 or whatever.
