Have you considered process separation for the engine and the
"local GUI" ? At least an option to run aeolus with no gui/x.

This is similar to how SooperLooper and Om handle bidirectional
OSC communication. SL has both the concept of single request
return values (by taking a return URI and osc path as arguments
in the request) and the concept of clients registering themselves in the
engine for changes to specific values, and for autoupdating of
values that continuously change. My register calls usually take
a URI and an osc path that will be used for the callback message
(with predetermined arguments).
It seems to work fairly well, I like the idea of all communications
using the same mechanism.
