Due to the big interest about using a Android tablet as a universal IR remote control I would like to share that at the end of April 2011 the Irdroid apprication and module will be available for beta testing. It is an unversal remote control app that can control TV's DVD's STB's, it is open source, free and it is based on the LIRC project. With the Irdroid module attached to your tablet will allow you to control your favourite TV or STB. See some videos at http://www.youtube.com/irdroid
