reuse apt-get cache

["Benedict Verheyen" <linux4bene@pandora.be>]

Hi,

i have a server and it has a quite extensive sources.list. Now i would 
like to make a cron job that does "apt-get update" every so often and 
then use that cache for my connected client so i don't have to download 
the packages list again and thus use unnecessary bandwidth.

Ideally this would mean removing the entries in my local clients 
sourceslist and have just 1 entry that points to my server's cached 
packages list.
Is this possible and how can i do that?

In the future i plan to make packages of my own scripts. Can i combine
those? I mean putting my packages in the cache of packages on the server
and thus also have them available for the pc's connected to my LAN?

Thanks
Benedict
