A simpler method than NFS would be rsync:
	aptitude install rsync # on both systems
	cd /var/cache/apt
	rsync -av . otherbox:/var/cache/apt # replace /var/cache/apt
					    # with $PWD if you prefer

Now this will get you in big trouble.  What if you have different
packages on the different boxes?  You'll get dependency problems.  The
simple thing to do after you've rsynced the apt cache is just upgrade
normally - it will use the cached files instead of downloading them again.
