oh, ok, because it can be kinda annoying having a lot of messaging app open just to send message to a single person (if I can't get him/her through gtalk/facebook, then i would send her a text message, hence there are 3 apps open). But I can still live with this. So everything is saved to tracker (I suppose this is an RDF store?)? then it should be possible to write an app to export a unified conversation log right? thanks for the prompt reply
