> Apparently P2P game updates ended up being disabled though. Probably a good thing too - imagine the absolute carnage on ISPs if places like netflix decided to outsource their CDN to everyone's home internet.
Given how asymmetric many home connections are, and were more so further back, and that using the whole upstream will effectively throttle downstream & there is no reliable way to detect at what throughput you will become a problem, I never saw P2P game updates as a good idea in general. Excellent for those behind the same bottleneck though - two PCs in the same student digs updating the same huge game for instance, saving a second slow download using the orders-of-magnitude faster local LAN - but I don't think that is a common enough use case to be worth the implementation effort.
I just recently noticed the delivery optimization feature in Windows 10. It sounds similar to what you are saying, sending Windows update to other PCs on the local network.
Yes. It makes more sense for something as ubiquitous as Windows, for which multiple devices running the same product on the same local subnet is a norm rather than a relatively rare exception.
