Comment 1 for bug 215661

I've another use case for this. I need to maintain multiple upstream versions of a set of debs for a soss distribution PPA (https://launchpad.net/soss). Since LP soss PPAs have a 1:1 mapping to Artifactory repos, this means that every new supported upstream version of a package needs its own soss PPA, a new Ubuntu PPA for building the package, a local Artifactory repo and virtual Artifactory repo. This is a lot of overhead, and non-deb soss PPAs do not have this problem.

Even if I still end up with multiple Ubuntu PPAs to build different upstream versions, being able to copy bits from those multiple build PPAs into a single soss PPA that publishes to a single set of Artifactory repos would be a very nice improvement.
