The two methods I've used to solve the same problem are

1) squid
  - you need to yum install, then briefly configure, then get it so the
livecd tool utilizes a yum configuration with the specified localhost
http proxy (or I think there was also a way to utilize the squid proxy
by getting some http proxy environment variable set correctly).

2) just maintain a mirror.  I use lftp to maintain a personal mirror of
extras and updates.  You could probably write a script to maintain a
subset mirror if for some reason you really wanted that, but (1) still
wasn't preferable.

I do think that this is such a fundamental aspect of doing serious work
with creating livecds that the interface for mirror/cache management
should be tightly integrated with the livecd creator tool (in the long
run).
