If the network goes down during the upgrade (which can happen while
NetworkManager is being configured, I think) you'll be stuck. Best to
keep that directory local.
If you already have a squid proxy, you can just use that. Just make sure
(a) the sources.list is identical, and (b) squid's cache is big enough
and allowed to cache the large files.
There's also a nice-looking project call apt-zeroconf in which each
computer in the network shares a list of the packages it has already
downloaded, but it's still beta with the very occasional reliability
issue. I still use it though :)
