I finally got around to actually trying to code this.  I now can determine
a source package for a binary package, and then go through the list of
changed source packages and pull their respective versions.

The issue I'm running into now, source-version combinations are not
available on changelogs.ubuntu.com.  So far, in limited testing, I've
only found 1:
   lazr.restfulclient at 0.9.11-1ubuntu1
The directory listing [1] shows only a
'python-lazr.restfulclient.copyright' file, but no 'changelog' like other
directories do.

Anyone have a reason why that particular changelog would be missing?
I *can* get at the diff of a changelog via [2], but I had really hoped to
get the full changelogs.
