Carlos wrote a script in response to the above thread. It changes CMYK black, and grayscale black to a swatch called "spot black". It's awesome, but it's only aimed at paths. I've made some adjustments to prevent it from effecting white and unpainted objects. I'm going to need it to work on text and gradients. Right now I am working on text.
I've tried to use the same logic that works on the paths on text, but I'm missing something. Help help.
This is the latest working version, it does not effect text or gradients.

This is the version I'm working on now where I'm trying to include the text.
