Hi there, I'm one of the two creators of TV.js
It's nice to see it get some love on HN, given that we just hacked it together from "scratch" yesterday.
I just wanted to clarify a few things briefly, this application is not intended to run on an Apple TV, it's meant to run on Desktops, Laptops and Raspberry PIs.
There's obviously a lot of room for improvement but as of now it works well, but the install process is relatively tedious (ok for developers, not so for others).
The application uses node-webkit to run as an App, we will possibly distribute bundled versions of this in the future.
And for those who may be asking, this is not our Startup, it's just a nice hack, we put together during our own personal Hackathon :)
