It can be worse than that: if a monopoly owns the poles, you're going to have to bury your fibre. That will cost you something like $800,000 per mile, more if you have to cross a road. In my home town, Chatham, Ontario, the local ISP is installing fibre underground because the duopoly of cable

Another point they missed: on earth, we can use conductive cooling and transfer the heat from the machines to a flow of air. In space, we can only use radiative cooling, and we need to be out of the sun to have enough temperature difference. --dave On 4/20/23 07:10, Hesham ElBakoury via Star

When I was in the reserves (in an era of dinosaurs and stone axes), the regulars were using encrypted, frequency-agile radios. They were hard to localize unless you were so close that they were the loudest thing on the airwaves. Using Starlink from a fixed location Could Be Bad. --dave On 2

I think that gamer experience doing simple (over-simple) tests with CAKE is a booby-trap. This discussion suggests that the real performance of their link is horrid, and that they turn off CAKE to get what they think is full performance... but isn't. https://www.reddit.com/r/HomeNetworking/com
