Could somebody point me in the right direction please...

I am a teacher and want to create a ?simple? vb program that will allow me to remotely view students screens, in my classroom, from myPC. I know that there is software avaiable, but the college won't pay for it and two eyes in my head are never enough!

What will I need to research/learn in order to create such a program
What kind of information will I need to think about (login details etc)

Is this too vague or too big of a project if I'm asking these questions?

Thanks in advance
