The largest issues for folks working remotely (work and school) at the present time focuses a lot on upload bandwidth as well as the latency you mention, Steve. Audio and video are particularly susceptible to latency and jitter issues. When you have multiple folks working simultaneously, that adds "extra fun" to the mix. I sure don't miss DSL and other lower bandwidth solutions for sure and am thankful that our service here is symmetrical because it's fiber based, especially since Professor Dr. SWMBO is teaching remotely and has been since last January, often at the same time our younger daughter is fully immersed in her university classes which have been virtual for the same time period. If I were not retired, I'd be adding to the mix, too, and given I was in the telecommunications industry selling (and using constantly) audio/video solutions which were fully IP based. (I worked virtual for almost 21 years, actually, but it was a lot easier in the last ten with all the nice tech to support it. And a fiber connection.
