I was wondering it anyone knows of a solution to this? I was an XBMC user on an Apple TV1 thanks to the FireCore hack, and from that I had two really handy options.
Because of the XBMC, if I was ever on Youtube, I had a Google Chrome extension (http://goo.gl/4g0AZj) which added a Send to XBMC option (you had to have the Youtube app installed on the XBMC for this to work mind you), and could watch it on the TV instead. Additionally, the XBMC folks produced a remote control app, and on Android that gave you sharing options to beam it to the XBMC machine, and watch it on the TV instead.
So, with my Apple TV3 having a pseudo "client" now with PlexConnect, is there a solution similar in this type of Plex ecosystem?
