Perhaps a little bit.  But rsync is very efficient and the mirrors
that offer rsync have fat enough pipes to handle the load, else they
shouldn't offer rsync as an option. :)

This is not a problem, as yum on each box will check the gpg signature
before installing any packages.  All the mirrors that you would
normally use are using a mirroring tool like rsync to get the content
from the master download server anyway.  Many of them don't run Fedora
at all, I'm sure.  So they'd have no way of calling yum or rpm to
check the package signatures.

Personally, I like keeping a full mirror of the release and updates
trees for the distros I have in service.  I use rsync to keep them up
to date.

If you have a Fedora Account, you can create a private mirror.  This
would be returned to your clients when they hit the fedora mirror list
and asked for a list of mirrors.  I've not used this before, but it
seems like it would be handy.

Another tool to look into is InstantMirror:


I've not use this either, but AIUI it is intended to automatically
populate a cache of packages that your local users request, so that
you only have to download a package once.
