Screen mirroring to TV or Roku?

view story

http://forum.xda-developers.com – Anyone know of a way to mirror the screen from the Maxx HD to a HDTV or Roku box? Something like the apple airplay equivalent. I just got a Roku box and have been playing around with it and I have used apps like Twonky Beam and Juice, which will beam content like music or pictures or video that's stored on the phone to the Roku. But I want to be able to stream anything that's on the screen, like play a concert from Concert Vault on the phone and stream it to the Roku. (HowTos)
