I hope one day all our connections will be fast enough to do a live stream of this caliber with friends. Granted, I realize it's all recorded and put together after, but wouldn't it be neat to be able to do this in real time?
Why is this not technically feasible with say, twitch? if it could be programmed to have a group audio chat that could be listened to by viewers. Then it would combine the people's livestreams with a selectable tab on the side for selecting stream. if a lower quality camera shot was used with low upload requirement, the video shots could be used and perhaps used as the stream selection.
