NDI Support?

I just became aware of NDI from NewTek (https://www.newtek.com/ndi/applications/) and I gather that it's become increasingly popular as a way to detect sources and control devices and process media streams with a common API.
I'm curious whether you have heard of this and noticing any potential sources leveraging this API.
