Yep, that's annoying and it's one of the reasons for the flat cache
design in apt-cacher: if clients fetch the same package from different
mirrors it will cause a cache hit since the package names are the same.

However, something that was raised at Debian Miniconf2 (IIRC) was that
this allows cache poisoning: by creating a compromised package and
sticking it on any random web server, a cracker can then fetch the
package themselves through the cache and any user who subsequently
fetches it (even using a genuine mirror in the sources.list) will get
the poisoned package.

Good argument for package signatures.

Cheers  :-)
