They finally implemented (at the request of countless dialup users) a 
method of storing a series of recent diffs the package lists, so you 
only need to download the parts that's changed. In prior time, there 
used to be a script apt-rsync that people could use for that. This is 
less CPU intensive on the server because it uses static precomputed 
diffs.

They haven't come up with any similar solution for the .debs themselves 
yet, but that sounds a lot harder as most people can't keep the old 
debs lying around on their system to diff against them.
