Charles,

I have written tutorials on just that.  I use apt-cacher on a central
host and tie the other hosts to it.  You do have to update the
sources.list on the clients, but its a really small fix.

Two links from my blog to get you started:

http://ubuntu-tutorials.com/2007/10/03/saving-bandwidth-with-apt-cacher-revisited/

(the second link will publish on the blog tomorrow)
