It depends on how much you are streaming. I can stream 1080p fine on my 20Mb connection but 2 1080p streams and the internet is basically unusable for anything

It depends on how much you are streaming. I can stream 1080p fine on my 20Mb connection but 2 1080p streams and the internet is basically unusable for anything else. If you have a street full of families with everyone all streaming 1080p near constantly you are going to need to greater capacity. And that's only at 1080p, what about high resolution 4K displays etc? What about when as well as keyboard and mouse input you want to send output for high precision accelerometers , biometric data etc etc.
