you could host just the hashes for the external files (signed with
your key) on your site.  then you wouldn't have to duplicate
upstream's data files nor spend (much) of your own bandwidth (since
the hash files should be fairly small in most cases).

or maybe there could be a hash.debian.org or a project on alioth to
centralize the hashes?
