But at first I'll write all my thoughts about future of this project.
It seems like evolution of this project goes exactly that way as I planned. I write an engine - you write a nodes.
This project is pretty close to v1.0 release. I'll try to finish it at this New Year vacations (here in Russia nobody works from 30 Dec to 10 Jan, so I'll have a lot of time to do it) ;)
I have no plans to make a significant changes in the engine. Here a list of changes which I plan to implement:
- Add Average mode to processInOut function (I didn't check Karsten's version yet, so I know will I write a new method or use an existing one)
- Add an external nodes autoload
- Improve .nod file loading in the case when some nodes are missing

Upd: Forgot to say, that I don't like idea about logical variables type. I think it will be much better to use numarray type for logical operations. X>0 = True, X<=0 False.
Anyway it's not a final decision. We can discuss it :)
