If you could combine it with power control functionality it could make a 
pretty cool DIY iLO[1] alternative.  Though it looks like you can do 
most of that with Intel Management Engine[2].

I was interested in using it as a transparent pass-through device so you 
could plug it between the presenters laptop and projector and use that 
as a source for OBS[3], so you could combine video of the presenter and 
slides.
