b), and offer an easy way to do this: hand one (or more) .changes
file(s) or a local repository to a wrapper script and have that torture
all the packages found in there with piuparts. Maybe give a hint if you
are interested in testing upgrades from something else than stable,
testing and unstable to your packages.

once that works sufficiently well, we can do a), too.

automatic
