Update a pacman database on a machine with no internet.

Question

ok, I'm not sure how many of you are going to find this useful, but here is what happened.  I have 2 Arch boxes running, my laptop and my desktop.  My laptop can get online, my desktop can't; due to I can't find a modem that will work with it.  so how am I supposed to keep the desktop as bleeding edge?  Easy, move the packages and pacman database to the desktop from the laptop.  Now, I don't do this everyday, maybe once a week (after a major version bump, or something).  I don't konw about you, but I would constantly be re-looking up all the switches I need to do this properly.  So I wrote a script; well two actually.  The first, is a simple bash one liner.  The other is a little more complicated.  You can find them here: http://mckean.upb.pitt.edu/~jhs/rph.tar.bz2.
I've been using them for about 3 weeks or so, and haven't broke anything.  But these are use at your own risk.  The import does  make a backup of your database, but the first few times I would suggest making one yourself, just to be on the safe side. 
Please leave feed back.

Another option: I use NFS to share my pacman cache from my main computer to my other computers, then mount on the other computers. The main advantage is that all the packages are only using up space on one computer.  It works really good.
In your case you would need to mount the pacman database also. "/var/lib/pacman/" I think?
Just thought I'd share what works good for me.
Here are my notes I took to remind me how to do it.
How To Setup NFS to share & mount pacman cache on other computer
======On main computer============
# pacman -S nft-utils
/etc/rc.conf
DAEMONS(… portmap nfslock nfsd …)
/etc/hosts.allow
#---For NFS Network File System, Linux shares----
portmap: 192.168.1.51
lockd: 192.168.1.51
rquotad: 192.168.1.51
mountd: 192.168.1.51
statd: 192.168.1.51
/etc/exports
#---share pacman cache -----
/var/cache/pacman/pkg 192.168.1.51(rw,no_root_squash,subtree_check)
======On Other Computer ==========
# pacman -S nft-utils
/etc/rc.conf
DAEMONS(… portmap nfslock nfsd …)
Note: only portmap is needed for mounting a share
Note: put portmap before network if automounting in fstab
delete cache "/var/cache/pacman/pkg"
mount cache
# mount192.168.1.50:/var/cache/pacman/pkg /var/cache/pacman/pkg/
check it
# ls /var/cache/pacman/pkg/
Automount in fstab
/etc/fstab
192.168.1.50:/var/cache/pacman/pkg /var/cache/pacman/pkg nfs rw,addr=172.25.1.150 0 0
