Comment 15 for bug 84900

It looks like there are more people already in the process of trying to get jack promoted back into main (actually, it was in main before, but got demoted after breezy).

Also, I heard it is possible for a source package in 'main' to produce some of its binary packages in 'universe', and depend on packages in universe for those targets. That might make producing a libasound2-plugins-extra (or -jack) much easier.
