I'm glad to hear - it means IDLE meets its goals :)

AFAIK and as far as 10 minutes of Google-ing can tell, this hasn't been
done. But I don't see any reason why this would be a Bad Idea.
As for thoughts on the proper approach: This could be an IDLE "extension".
See idlelib/extend.txt for an introduction to extensions, and check out some
of the built-in extensions, like ParenMatch and CodeContext.
For some technical details, check out EditorWindow.py:
self.per = per = self.Percolator(text)
self.color = color = self.ColorDelegator()
self.color = None
What your extension should do is call per.insertfilter(custom_colorizer),
where custom_colorizer would be your colorizer object. Your colorizer class
should inherit Delegator - see Delegator.py. Also see the implementation of
ColorDelegator in ColorDelegator.py, for a starting point.
Feel free to bug me with questions, I'd be glad to help :)
