My plan, if I ever need long haul(>3meters) video or audio links, is to get the signal into ethernet(or even better ip) and use common network equipment to transport it.

The theory being ethernet is such a well developed, easy to source common jelly-bean part that this would trump any gains that specialized transports might otherwise have.

But this is probably just my inner network engineer being disdainful over unfamiliar transport layers.

Nah, this is totally the reasonable way to do it, iff you can tolerate the compression loss or whatever. Because 4k60 is like 12Gbps uncompressed, and even more after you cram ethernet headers onto everything. So most such devices include some compression, and the really expensive ones let you configure how much.

Failing that, you're probably doing SDI over your own lambda.

It's much cheaper to just buy an optical HDMI cable if you need a long point to point run, it's like 50 bucks for 100 ft. The cool stuff you can do with HDMI over IP lies in switching the signal to different endpoints on demand and things like multicast to multiple receivers, both of which are things you can do with off the shelf HDMI over IP gear.

That is happening in the pro world, check out e.g. SMPTE ST 2110.
