I have an application for which I need to be able to break a Gnu buffer into
multple sections. Although the buffer should act like a normal buffer in most 
respects, I need to be able to do certain things on a sectional basis: Add a 
section, delete a section, set read-only mode on a section, go to a section,
collapse or expand a section, and so on. A few operations that normally are 
associated with buffers also need to be moved to sections. For example, I need
to keep a modified flag for each section, rather than the whole buffer. I'm
told that some other emacses have this capability (zemacs ?) although I've 
never used  one that does.

So, my question: Before I embark on what may well be a major hack to Gnu emacs,
has anyone done this already or tried to? Can anyone give me some info on emacs
versions that support this capability that would help me keep from completely
reinventing the wheel?
