I’ve just released the RedditTV for android app. It makes YouTube videos popular on reddit.com easily available on your android device.

Got a Media Center with a big screen?
Now you can even send the video from your phone and directly to your Media Center! Just long-click any video you want to send.

Currently supports:
-Google TV
(requires Google TV Remote or Logitech Harmony app)
-XBMC
(requires configuration of connection parameters in settings)

Please upvote the related reddit post and provide feedback on existing or new functionality.

Most likely, the code will be open-sourced in the future.
