I am working also in a Python Nodal Framework that works similar to ICE, and it works inside maya or any other app with pyqt/pyside.
The original code and repository is from this guy : [ Ссылка ]

Wich is amazing!!
I have forked the project and added a lot of new features that make it more softimage ICE similar, like dynamic port types ( one node for multiple cases ) , subgraphs ( compounds , exportables,reusables ), fixed the python node and added the ability to export as a native node ( pure code ), also a lot of navigation fixes ( middle click selects branch, ALT+drag copies nodes, Copy-Paste betwen graphs/compounds/sesions, selection add/remove Shift/Ctrl, etc ), collapsible comments ( ok thats not xsi but yes houdini ;) ) , and lot more...
Theres a lot more things to do but hope you like it
