I'm a student at a small high school in Denmark, im the only one using Ubuntu, but I'd like the other students to at least try it.

So I asked for permission to set up a small group of computers for the others to try, mostly for smaller school tasks, or random internet surfing.

So far they've let me set up 4 computers, and I would like to manage all the computers from a single computer which should also work as the "picture" for the other computers.

i need software to manage this, as mentioned below is VNC as an opportunity, but what i get from reading about it is that this kind of soft ware is just sharing a screen (which is hopefully wrong)

and what equipment would I like to use?
