Confreaks is a great resource for watching Ruby presentations from conferences around the world; XBMC is a powerful media player which you can use to enjoy them from the comfort of you sofa.
Just download a release from releases
, and use 'Install from zip file' in XBMC -> System -> Addons.
Please note that this addon has only been tested with XBMC 11.0 Eden.
This plugin uses xbmcswift2, a "A micro framework to enable rapid development of XBMC plugins". Thanks to Jonathan Beluch for this.
