How to share desktop over LAN to multiple viewers [closed]
Solution 1:
You can stream your desktop using vlc in conjunction with the screen:// input access module (gets screenshots from the primary screen) as a (multicast) streaming server and then use vlc again on the desktops as a client. There is a fair number of walkthroughs on the net for this, here is an example of a rather decent one:

Solution 2:
I would go for Teamviewer as it allows a presentation mode and works in lan-only environments.
Check www.teamviewer.com
Not sure if this is available in the free version though...
