Those are usually quite expensive. If HDMI requires 48Gb/s capable transceiver chips to be built into every TV, they will get really cheap very fast. It might not be a viable solution in the end, but it could work for some applications.

Over typical HDMI distances, you don't really need an expensive transceiver. 100GbE can be done over direct attach cables that cost less than many current "premium" HDMI cables. Much of the cost beyond that is related to the MAC and host interface being able to do something interesting with the packets.

40 gbps is only Infiniband QDR speeds, you can pick up an adapter for sub-$50 right now.

And plug it into what?

Your servers?

If you mean switching, you don't need a switch for simply connecting two computers. Presumably that was the use-case supported by "HDMI-as-network-layer".

If you watch around, you can get Mellanox Voltaire rack switches for $200 or less. QDR gear is "obsolete" and often surplused at very attractive prices. Everyone else has moved onto FDR or EDR speeds.

Your can get e.g. a qlogic qdr infiniband switch for a few hundred dollars
