My practical concern is many people are uplink choked. Technically, on 200 Mbps down, I was supposed to get over 10 Mbps up on Comcast Xfinity but practically it was closer to 5 or 6 Mbps. This is already problematic if you have more than two video conference calls going on at the same time. I am moving soon to a Spectrum / road runner area and we are supposed to get 400 down and 20 up. Let's see if it helps. I don't think I have the capacity to run a node if I understand this clearly (please correct me if I am wrong). I imagine the way a relay works is you download something from a source node and upload it to the destination node where source and destination are somewhat randomized?
