Apple TV 3 DNS Workaround

I’m just catching up with people who are pointing their ATV to a custom DNS server through the native Apple Trailers app. The DNS I have added allows me to add custom feeds via a web interface with login.


This seems to be a viable solution as you can point the DNS to a properly configured local web server. 
Could this be a service? Allowing users to launch their own web server that uses Apple Trailers application.js file. Seems like a great way to use Plex.


My goal is to extend the desktop using ScreenRecycler VNC but I need to be able to launch this somehow without a jailbreak, or with.
