Well, as long as your ethernet is fast and not jittery it sure seems like an ideal solution. I guess it all depends on the absolute resolution you have to have on a guaranteed basis.

Instead of interrupting power, they are sending a “pulse” of power per sync pulse. I don’t recall the details on it at this point. CMM5 FYI is looking like December availability now.

There are two types of sync over power. The first is being called Canopy sync, which is compatible with the 450i and earlier radios. The second is being called Cambium sync and is compatible with the 450M and I'm guessing later radios. Currently there are devices that produce the cambium sync pulse... The CMM5 and I'm about 100% certain that Last Mile Gear has one as well. I have the technical information I need, just haven't had a chance to get the circuit designed (I only received it shortly before wispapalooza), let alone tested.

So, you either need to use timing port sync (via the aux port) or use what they're calling cambium sync. The 1U injector is very close. I need to finish validation on the latest board revisions and then will be releasing it to production assuming there isn't some showstopper I missed.
