"Need" is pretty heavy handed.  Your example is rather fringe, honestly.  It
immediately strikes me as something you should do as a mini-modular system.
Define a very simple plugin system (you don't need to solve all the problems
that GMPI does) and make them all mini-plugins.  Then wrap that all in GMPI.
Very much how Reaktor, Tassman, VazModular etc. do for VST.

?  What exactly do you mean by 'flow engine'?  The ability to load
sub-graphs should be trivial.  If it is not part of the SDK, then a
GMPI-host plugin which loads sub-graphs will be one of my own first
projects.  Stop fretting, if that is what pesters you.  If it is something
else, then you ned to be clearer.

The actual graph-processing code my be examples in the SDK, but I think that
this is one area where hosts will do their own thing - threaded,
non-threaded, etc.  We can and should show a simple example of traversing a
GMPI graph, but don't expect that to be the one-true algorithm.

I feel like I am misunderstanding what you want..
