I was really pleased to see this blog post today, because I was looking for exactly this a few weeks ago and was sad to find it didn't exist. Now it does!
Displaying on an external screen via wifi is a really handy thing that is increasingly commonly available. Lately I'm finding most TVs I run across - including hotel room TVs! - have the feature available. For whatever reason I don't really see many people using or talking about it, but it's great - you can watch videos from your phone or laptop without having to carry an HDMI cable around everywhere and hope the inputs aren't blocked or full on the TV.
So I'm looking forward to testing that out, and hope all the bits land in official distribution packages soon :) Thanks Benjamin!
