Hmmm, I'm not convinced on this, Bit Che would have to create a second api interface that other programs communicated results to it through. Furthermore it would be potentially fraught with security issues, Bit Che could not guarantee the safety of a closed source independently compiled self-executing module. Not to mention there's the potential of corrupting Bit Che in some way if the interface isn't well designed enough.
Would it not be more practical to make the scripting language even more powerful than it currently is?
