I like the concept. Are you going to integrate it with existing platforms? I think that should be the way to go. Offer your tech to other apps that already are working with teachers and students.

My worry is competition. If Googlehangout creates a similar product via an extension, competition maybe super fierce. Nice try!

There are other collaborative whiteboard platforms. Not sure how they differentiate themselves. They can do it by probably focussing on the classroom setting and building features for that. Curious how they built the hover pad too.

Love the concept, particularly using the Hover device. Would have liked to see more explanation of how this could be promoted and used by multiple industries, since this is a flexible solution.

Online collaboration. Don't the impact of the product will be high. There are a lot of free tools available aiming for schools and students
