With the powerline ethernet adapters, OTOH, I just plugged them in and everything Just Worked, much slower peak speed, but nice and consistent and more than enough bandwidth for HD movie streaming.
Powerline networking is still a shared medium. You're sharing the available bandwidth with all of the neighboring houses on the same utility transformer.
It does have the benefit that signal strength drops off with linear wiring distance. Thus, you're farther from your neighbors than you would be with Wi-Fi.
However, as with 5 GHz, you're getting good results right now because powerline networking isn't too popular. But if every house were to get powerline networking, then you would start encountering interfering networks.

Yes, but not enough attenuation to block powerline communications. This is not a theoretical concern. People have tested HomePlug units and successfully connected to neighboring houses. There's even explicit provision in the spec for neighboring networks, so that they share the bandwidth instead of stomping all over each other.
