Great idea, but I'd say practical applications are limited..

Industrial sensors shouldn't rely on Wifi. Hospitals shouldn't rely on WiFi. In a car just run ethernet alongside power.

Since you can't guarentee wireless maximum latency on WiFi, I still wouldn't use it for multi-channel audio (only multi-room, which NTP is good enough for anyway probably). Especially a problem if you want to sync against Video.

So its a nice idea, but it will probably affect very few people..

The playback buffer size is usually much larger than the wi-fi latency. This should allow multi-channel and video to sync without issues.

That still introduces other issues though. You will probably need larger than 200ms to be safe, which will make the setup annoying for applications such as gaming.

Or it would need great error correction. Either way, wifi equipment needs to accept interference (nothing you can do)

Well, considering Sonos has multi channel and multi room capabilities wirelessly, it can work. That said I have no idea how this spec works vs whatever proprietary magic they've got going on.
