Will Natty's Unity Dash have wine integration like the ubuntu-desktop session? It would be nice if it had it's own category for Wine (if installed).
The answer, bluntly, is "No, unless Mark gives me a job."
I've had designs for better integrating Wine with Ubuntu for some time, however progress has been slow as it's an awful lot of time and most of my day is spent doing "real work" and the day to day tasks of package maintenance. You can see some of this such as integrating Wine into Software Center (might not be finished by Natty), or the better Wine integration specs.
It would be neat to use things like the Unity Places API to make Wine really slick, but at the moment I barely have enough time to make sure things aren't horribly broken.
