uh, except, where would the script be invoked, in the current scheme?

do you have it wrap shutdown?  if so, how do you get periodic
warnings to clients (did sun implement that?  i forget), or (if not)
how do you get the right-before-shutdown warning?

do you have it wrap wall?  what happens if somebody wants to use wall
in the normal fashion?

etc.

I don't see you can get the client warning functionality, without
modifying the shutdown sources...  (I also know exactly why you
_wouldn't want_ it, but if some people want it, it's not for me to
tell them that they're running their machines improperly, and i don't
think it should be impossible to do w/o modifying sources...)
