Raspberry Pi Computer for Guests?

Hi Man,

wouldn't use raspberry. Get some old computer spots put Ubuntu on them and done.
For a media library instead of DVDs, use pivos. Very good with online updates and stuff, will run the XBMC. Very powerful media entertainment system.

Jukebox, don't use internet radios, buffering will cause more damage then everything else. Silverjuke is for me the best solution. Good software with kiosk mode. If you have a backyard, setup a computer only with mouse and this software will do the rest for you.
