Hi;

This is an intersting discussion. There is another node base visual programing called Dynamo. This is an open source and currently works
as stand alone ( you can export your model in STL format) or with Revit integration. Someone also has created the integration between Dynamo and Rhino called Rhynamo.

See links for Dynamo info:

https://github.com/DynamoDS/Dynamo

http://dynamobim.com/

There are possibility to integrate this progoram with other software, see Link

https://github.com/DynamoDS/Dynamo/wiki/Integration-Guide

It might be difficult, but may be there is possibility for an integration between Dynamo and MOI.
