| Kick ass to see progress continuing on this great Miracast

| It's unfortunate the industry as a whole never really got their
| stuff together on this- while I like the thicker client model
| that, say, a Chromecast has for many reasons (not trying to
| stream media live is a win), having streaming media as a baseline
| tech seems straightforwardly sensible & universal, and we
| probably would have advanced wifi & streaming considerably if
| this had started seeing wider adoption. It was a reasonable
| enough wireless-cable-substitute.
|
| There's a PR for getting Miraclecast working as a source for
| external displays, which would be a great addition.

| Miracast was cool... while it lasted. It had some issues as a

| ComputerWorld sarcastically put it, this was "to the immense
| disappointment of approximately seven people"). Miracast is still
| functional on Windows and Linux... but how many people use it?
|
| The best effort, though little known, was Microsoft selling a
| wireless stick for $49 that would connect to your TV and only
| supported Miracast. However, the latency was never near as good
| as Microsoft portrayed (watching a movie over Miracast generally
| isn't fun). They still sell it apparently, but now only for
| business uses: https://www.microsoft.com/en-us/d/microsoft-
