Here at SCS we have a use for such a beast.  Not very much use, but
still It would get used.  We also have need for a real word processor,
thanks to ``word.''

I am currently writing an editor/wp (have been to 2 years!) and it 
takes very little extra to add this featrure.  The buffer has a bit that
tells if the line is shared or not.  If it is shared it has more data
in the structure to keep people from trashing each others work.  The
basic idea is that EACH line can be marked READ-ONLY.  Of course the
insert a line makes things real fun and since the data may be on the disk
and not in memory, that has to be accounted for.
