How often are more than one plugin with the same control inputs used in
paralel? I was rather thinking of colapsing (or swapping) plugins in
series. They'd have to be linear and time invariant, of course.
Or maybe plugins could 'know' how to colapse themselves, sort of like
overriding Plugin::operator+(const Plugin&), to use a C++ metaphor.
