[Tiller, Michael (M.M.)]

Please keep us posted on your progress.  It would be great if you could
share what you have as well.  I general purpose framework for creating
ANTLR based editors (with all the bells and whistles you describe like
outlining, etc) would be a really great contribution in my opinion.
