HD over 3G/4G LTE cellular connection? The lag would in the order of a few seconds, which makes flying FPV extremely difficult. It also means a huge data bill unless I've been grandfathered into a "unlimited" data plan.

I think I'll just stick to some of the cheaper, well respected 5.8Ghz FPV setups.

We get below 150ms end-to-end latency. Check out our project page where we describe what we do different to achieve this.

Is that network latency or video latency?

real perceivable end-to-end video latency

There are ways around the lag issue on LTE, but you are correct, it's going to be a bit expensive for the hobby market.

As mentioned above, LTE latency really isn't that bad. Just most implementations on top of it usually result in high latency. I think we avoid this pretty good in our project.

Have you published any details about how you accomplished low latency? For example, you stated 150ms further up in this thread, what were the conditions for that test? Was it documented?

As sweet as low latency HD FPV would be, I'm hesitant to spend more money on a "newfangled" digital solution unless I I'm aware of such technical details.

I would suggest to read "The geeky stuff" section on our campaign page, it explains how we achieve low latency. If you want to know specific details I am happy to elaborate.
