Solve : sound over LAN?

1.	Solve : sound over LAN?
Answer» HELP me ..SOMEONE please..! I am starting a Spoken English class and i wish to impart training on a ONE to one basis to my 30 odd students. They would be in individual kiosks with a headset and mic. They would also have to be able to talk to each other under my supervision. How can i make this possible at the least possible cost? Also, at a later stage, each kiosk would have a PC too! How COULD I then have this arrangement on a LAN? Would someone tell me please?How Home Networking works http://www.voip.org.uk/reviews/category/getting-started/ or this even>>http://www.microsoft.com/speech/evaluation/techover/ http://www.idirectshopping.com/products/talkittypeit/titi_101_nopop.htm?extra=
