Well sure. I guess I should be more specific, but the points was that as long as it works in a local Ethernet network, you are fine, as you can fix it reasonably easy by just encapsulating packets. And as long as you don't encrypt, you don't even need much/expensive hardware to handle e.g. 10 Gb/s Ethernet over an IP network. If you just have a passive thing that translates HDMI connectors to RJ-45 connectors, Ethernet won't help you. But if you use Ethernet, you can also use IP. That is all.
