network paging type software?
consider the scenario,
teacher is in a computer room, has a crazy class, needs help, there's no telephone and she doesnt want to send any kids out.
Currently the only option in this scenario is to request help by email or helpdesk but there's no guarantee anyone will read it in time.
What I want is some client server software that the teacher can type in a box and it will either pop up or alert in some fashion on technician's computers. I've looked at internal IM in the past but they're somewhat over complicated to the job as no interaction is required however there may be other uses for such a system. winpopup stuff is disabled, so the answer isnt there.
Anyone know any free software like this? or failing that use some sort of internal IM. thx.
