Right, thanks.

Exactly! All I'm trying to say is:

I want to assign to the margin

1.- any kind of data (not just line numbers)
2.- on a line by line basis
3.- efficiently
4.- from the lisp level
5.- with an interface that does not include lots of overlays or, worse
yet, text-properties (which implies modifying the buffer)

Actually, I think that line-numbering, and marks to show state for the
line (if it is modified, or has overstepped the margin, etc.) are good
uses. What I'm not seeing is good uses of the current interface to the
margin.
