Another thing I thought of which might be useful is a way to protect
areas of the display, so for example if you are using a widget like
select-list you can't move off the list until you accept something or
break.  I think you could do something like this without too much
difficulty by using a special parameter like $PREDISPLAY (maybe also
$POSTDISPLAY, since this gives you more control than zle -M), which would
insert the given lines before (or after) $BUFFER.  This could probably
be done within zle_refresh (and zle_parameter, of course).  It would
probably have to be line-orientated to avoid weird interactions with the
normal buffer, although maybe even that restriction is avoidable.
