Topic: MythTV front end/LCDproc replacement
Some people use LCD screens to show what is being recorded/played on MythTV; this could do the same thing, and maybe make it mo pretty. Often the utility that drives the LCD screen is a publicly available program called LCDProc. Having a 'Chumby' port may make a small number of open source projects displayable on the Chumby.
(Granted it is overkill, but there are some similarities between LCDProc and Chumby, such as rotating content.)
