Hello. I've just successfully injected plainbox into the python-modules directory [1].I've filed an ITP bug and I'll shortly correct the changelog to reference the bug number. You can find the git source corresponding to the package that was uploaded on [2]. I'm also available in #debian-python to answer any questions that you may have.
