@bradleyland - thanks for the comments on the site. We've implemented some of those changes already. As @davidandgoliath said, there is a demo on that page - I've removed the video so that's more obvious (and added the video to the initial blogpost).

Encouraged to see the reception here - Airtime is at an exciting and sustained moment of development right now, so plenty more new features in store for the next 12 months, especially with regards to live broadcasting.
