I discussed the idea a bit with James Troup, and one of his concerns was that
the database would be centralized, not distributed over many mirrors like the
packages themselves.  This would be a scalability problem if such a system were
to become popular.  Judging by the response that apt-listchanges received, and
the interest people have in the idea, it just might.

As you suggest above, maybe the solution is to use a file-based system rather
than an interactive database query as I had envisioned.  Package changelogs
could be extracted from source packages and stored (compressed) in the archive
somewhere.  Then, retrieving the changelog for a package would be as easy as

Some changelogs, like those in the XFree86 packages, are over 60kb compressed,
but most of them seem to be less than 10k, according to a quick manual survey
on my system.
