That would work, and work well if, and only if all of the machines had 
the same software.  Your DNS server/s don't need apache, your SMTP 
servers probably don't need any database packages and the workstations 
have their own specific needs.  What would probably work best is to 
create a local repo that contains all of the new packages for what one 
might call the core programs that all of your boxen need so that they 
only have to go to the Internet for the specialty packages.  I wonder if 
there's a way to make fedup understand that.
