Try Hotline, it's fantastic on an Intranet/Lan environment.
You can:
- send private messages to each person
- or send messages to a common message window
- you can have a "news room" for news you want everyone to see (eg newsletter, pricing list, announcements etc)
- and it's all damned easy to set up.
- Each person can choose their own icon/picture
- Others can see when messages can't be sent to that person (eg in a meeting all afternoon)
- auto-reply can be set up
- filesharing is a breeze via Apple directory style layout
- each user can have their own file folder
The free version is the best version, I think the Hotline business model has recently changed to a buy-only one, check out:
