Viewing multiple iPods on ipad?

Hi,

I am an ICT teacher and I am currently researching the use of iPods in the class room. I feel it could be very beneficial for our students.

Currently I have a piece of software that shows me the screen of each students laptop so I can monitor and show my screen on their laptops.

Is there any software that could do the same thing with the iPods where I could demonstrate on all iPods, view their screen and exhibit their work or anything similar? Either with a computer or iPad?

Looking forward to a response.

Kinds regards,
Tristan
