Roast my demo - short preview of Meetopia

I've just posted a short video preview for Meetopia on YouTube:

In it I show some of the concepts I'm considering for Meetopia, an app to make meetings more productive and engaging.

In particular I am focussing on helping hosts run better meetings through best practice within a collaborative, real-time application.

I'd love to get your feedback so if you can spare four minutes please give it a watch and give me any feedback below.

Yes, I know it's a bit long and rambling, but I'm aiming to iterate the pitch so any feedback would be great.
