It's a project that uses libpd in JUCE, maybe you guys know about it.

I never got into libpd but I know it is awesome. I never had to make patches compatible to vanilla for it, but now I have a strong motivation.

So let me excuse myself to make the following silly question; you can include Pd externals, like zexy and cyclone libraries into libpd, right? What would be the restrains for externals? 

cheers
