While I think you are oversimplifying the timing issue, you are not the first to think that about 2110.

The engineer on the truck seemed to have the most annoyance with the PTP aspect of 2110, but it seemed nobody questioned the move to 2110, and at least as far as broadcast equipment goes, they're all in on 2110. As a small(ish) YouTuber, NDI is more exciting to me, but I'm not mixing dozens or hundreds of sources for a real time production, and can just re-record if I get a sync issue over the network.

Perfect is the enemy of the good, as always—reading through that site, it seems like no solution is perfect, and the main tradeoff from that authors perspective is bandwidth requirements for UHD.

It looks like most places are only hitting 1080p still, however. And the truck I was looking at could do 1080, but runs the NHL games at 720p.

NDI is indeed quite good for prosumer cases. As a Newtek (now Vizrt) shop, our Tricasters speak it natively and that's a great reason we've made use of it.

That being said, if you aren't already in the Newtek/Vizrt ecosystem, might I recommend exploring Teleport, which is a free and open source NDI alternative built into OBS which has also served us very well.

The “no standalone switch can give enough bandwidth” issue has generally been solved since that page was written. You can buy 1U switches now off-the-shelf with 160x100G (breaking out from 32x800G). One of the main drivers of IP in this space is that you can just, like, get an Ethernet switch (and scale up in normal Ethernet ways) instead of having to buy super-expensive 12G-SDI routers that have hard upper limits on number of ins/outs.

Of course, most random YouTubers are not going to need this. But they also are not in the market for broadcast trucks.

Yes its a huge benefit. Of course without an NMOS SDN solution, actually reliably routing so much data over a network (especially if incrementally designed) is a huge pain in the ass. But thankfully we have those systems now.

We sort of traded the big expensive SDI switchers for big expensive SDNs

		Also, I guess we traded a ton of coax cable for somewhat more manageable single-mode fiber. :-) I never fully understood why SDI over fiber remains so niche, e.g. UHD people would rather do four chunky 3G-SDI cables instead of a much cheaper and easier-to-handle fiber cable (when the standards very much do exist). But once your signal is IP, then of course fiber is everywhere and readily available, so there seems to be no real blocker there.
