I have several machines here running 8.04 and wanted to avoid more than one 2GB download to update to 10.04.
I used a very simple one-off solution: manual copy of /var/cache/apt/
On the upgraded machine, copy the entire /var/cache/apt/ to a portable drive
On the machine to be upgraded, first make sure current distro is up to date
Replace /var/cache/apt/ with the one from the portable drive
Start upgrade as usual
Profit! (2 minutes of download instead of 2 hours)

There are a number of post/articles about setting up apt-cacher, apt-proxy, or sharing /var/cache/apt via NFS, however these are harder to setup up, and I suspect more prone to breakage.
