some weeks ago, I decided to package Songbird.
Since that, I've been maintaining it in my PPA. In order to get it in Intrepid, we (the Ubuntu MozillaTeam) would like to, among other things, make it use our xulrunner-1.9 SDK package, but it requires some real efforts, and we have so many things to do.
In the meantime, preview packages live in my PPA.
Feedbacks welcome. Needless to say it's meant to evolve a lot, it's still pretty raw on my side.
(I'll bump it to 0.6 later this week, i.e. when upstream will have the branch tagged properly)
