[wellylug] updating vs bandwidth

[Atom Smasher]

here in the land of slow/metered bandwidth, what's a good way to keep 
ubuntu up to date with more than one installation?

also, if there's one system that's already up to date (and fairly generic, 
same cpu), is there a convenient way to create installation media from 
that? without downloading a new CD? i suppose i could clone the HD... but 
that doesn't seem like the best way when the hardware is different and i'm 
not really looking to clone the original.

thanks...
