[K12OSN] IP based PA system?

[Doug Simpson]

Interesting concept. . .

If the computers are logged in at the beginning of each period, it is 
possible to make them play a pre-recorded message at a certain time (login 
time) and it is possible to give messages based on computer names, etc.

At our school, we are trying to make a standard for computer names. . 
.(still getting there, but can't seem to get them named right when they 
are installed. . .).

So, for computers named jhxxx (where xxx is computer specific and jh is 
the class or building) they will get messagejh.wav and for computers hsxxx 
they will get messagehs.wav.

If the classroom must be interrupted during the period, those 
announcements are done over the regularinterrupting any class except the 
specific one(s).

You didn't say what OS is on the workstations or anything.

We have Winders on the workstations and linux as servers here and I do a 
lot of things based on computer names. I had actually thought about this 
but never got around ti implementing it.
