I'm currently writing a toy library to play with hierarchical graphs – if Ao is a minimal implementation of Antimony's CAD, this will be a minimal implementation of the graph engine. Beyond that, it's a small matter of programming – I'd want to find a UI paradigm / library that's less cumbersome that Antimony's, as the UI programming adds a lot of impedance to development.
