I'm including Dante/Ravenna/Livewire in that question.

My guess is that this is more an application toolkit for home/consumer applications instead of professional use, but a lot of the problems they have listed on their roadmap are already solved through a family of open* standards. The name escapes me but there's an industry initiative to provide FOSS APIs on top of web tech to build these kinds of applications. Engineering manager from Fox/Disney gave a talk about it last month (maybe it was march?) at the LA SMPTE meeting. Lots of money is going into this domain.

* with an AES membership, but you should have that for this kind of project anyway
