local Arch Linux pacman package cache

I was wondering whether it was possible to share downloaded Arch Linux packages in my home network, so that not every of my 5 hosts downloads from the mirrors. Advantages: saves bandwidth, no package duplicates, faster "download" of packages which are already the package cache to the client. (Note that pacman will actually not download packages which are already in the package cache).
