yes it is possible, I am doing it at home now ;

1. Use wget with the options -nd --mirror to download.;
Using one machine to download and keep adding newly developed update rpm 
packages (Keep coming out every week sometime in 2 days) into a local 
folder, this folder is the master folder holding all the update rpm 
packages for any and other machines, except first time doing a full 
download, after that every time new update are available, wget will only 
download those you still don't have in your master folder. For detail 
use of wget, use google and enter the key word "wget manual" and you 
will  find it and look through it.

2. Use yum to update the system with the master folder that holding all 
the update rpm packages downloaded.
You will  find the how-To in Fedoranews.org "How to build a custom Yum 
Repository in FC3" by Richard flude under Contributing Articles from 
Fedora Community,
Yum will use your downloaded update rpm packages in automatic processing 
(It is good even at the first time you do the update with more than 700 
rpm packages, that will take more than an hour, if you do it with 
up2date via Internet - I would imagin will take more than half date  to 
complete per machine!).

3. Update the other machine with the downloaded update rpm packages;
You have at lease 3 options;

Burn those update rpm packages into cds and use these cds to update 
other machine as step 2 , but you have to keep adding new update rpm 
packages into it soon as new ones are available.

Use rsync to synchronize other machine in a lan with the master fold 
which holding all the update rpm packages, this is what I am doing since 
I must do multiple backup data into other machine - a simple script will 
do . Except the first time doing a full sychronization (full back up 
actually), every next time will only synchronize the newly added 
packages. This is what I am doing as my update to all other machine with 
download rpm packages.

Or you can use yum in a machine which needs update, and point to the 
machine (In same lan) where the folder is holding all latest update rpm, 
I haven't tried it, but I am sure this is workable.
Hope above will help.
