It'll still be a series, just not a series of Ubuntu.  All it needs is
the ability to target series of a different distribution.  This will
involve:

 * replacing the "/ubuntu/" part of ppa.launchpad.net URLs
 * parameterising the various places that the "ubuntu" distribution is
   hardcoded in cupstream2distro/launchpadmanager.py
 * adding "distribution" options anywhere we currently have "series"
   options
 * possibly adjusting anything that uses pbuilder or similar to use a
   different archive mirror URL

You can look at the various tools in lp:ubuntu-archive-tools for a
model: pretty much all of those take -d/--distribution options as well
as -s/--series (or -s/--suite).

In some ways it would have been a simpler option, but the lack of
isolation from the parent distribution is really a killer.  PPAs weren't
designed to support this kind of entirely-independent use.
