Sure, but just pointing out that the ability to carry an ethernet signal does not impart the ability to talk on the network the hdmi might somehow be plugged into.

If you can provide an example of a receiver that does this that would help. I'd like to see actual usage of this feature before I start worrying about attack vectors. From what I can find nobody has implemented it.
