I get 100mbit connection at home via optical connetion these days so bandwidth 
is not the point.

It is about saving load to the remote host (a shared resources) which
provide data to everyone.  If you have many hosts at home, running cache
service for package deb fies are good idea.

apt-move create local package mirror with packages downloaded to reduce
duplicate download.  It seems good but I never bothered.

apt-mirror seems to make subset mirror of archive ... which needs to
require too much attention for casual user like me because it relied on
package name etc.

proxy server just hold all remote data requests made via it.  If it is
configured by http reuest time out in right way, you get good copies of
archive without specific package name requirement.  I used to use it
while not caching noon deb files.  I used to cache just deb files.
Simple policy is the key.

I am running single machine these days so I do not do this.
