Stephan Hermann has blogged about the new wine team and has created an Ubuntu-wine team on Launchpad. The Ubuntu Wine Team will take care about the WINE application in Ubuntu and plans to support all wine related projects as well.
He has also created a wine-doors launchpad project for this tool and pushed two bzr branches to the team directory and has plans to add a few upstream branches later this week. If you have a Launchpad account, you can join them using the Launchpad links provided above.
