It sounds like they take the same idea but are applying it to a Vapor Deposited Coating. So it should be more durable and you don't have to build a window and then apply the coating. It's in the glass surface.

Part of the issue with glass coating is the carriers that get used during production. Dimethyl Tin and Hydrofluoric acid are both extremely toxic and very common carriers. At least for Vapor Deposition Coating.

A bigger question is, imo, how finicky is that stack going to be to actually apply

The coating stack. In online applications it's deposited while the glass is still hot, before annealing.
Dimethyltin Dichloride. Pretty nasty stuff, really.
