I was using a feature in Skype where I could do video and have an interactive sheet open with a choice of red, blue or green ink to see who was drawing at the same time. I think this was 2007. I was overseas and was doing homework with my kids. It's still in Skype, but I believe only the business version or with Office 365. It was free then. I don't see many options now that are free and are interactive.
