Screen sharing for customers in a retail store

Hi,

I am starting up a new business - and I will need to do is to show customers proofs of their jobs. We had originally thought of doing this with a second monitor but we aren't crazy about mirroring everything we do on the customer's monitor.

My question is - is there a way to screen share pictures (either on another monitor or an iPad) where we can eaily and quickly just send the picture to our customer's monitor (or iPad) without having our every move mirrored?

Thanks,

Trevor
