I actually started on a PyQt4 facebook app but have unfortunately not had any time to work on it. The plan was to have about as many features as Bloo on Android.. I currently have it showing feeds and friends but it's far from ready to be used - the feed doesn't align correctly and all the text is squished... plus has massive lag when trying to download everybody's little pictures.. But yeah... I started.. unfortunately it's fallen by the way-side.
