RHN ( can handle this for you.  If you get all
your machines registered with RHN, you can log into the RHN webpage, 
and with a few mouse clicks tell it what packages to update on them. 
Your machines should be running the rhn client daemon, which will
regularly connect to RHN's servers and download the appropriate
updates.  up2date is a part of RHN.

If you're not up for paying RH for this service, I suggest looking into
yum (  With it you can setup a
local repository that you update with new updates from Red Hat.  You
then have a cronjob on all your machines to run yum, which will update
them off your local repository.
