[CentOS] yum-proxy?

Hi,

I've been using Debian for a few years, and there was one nifty little 
app that made installing and updating so much easier: apt-proxy.

Most of the time, I'm taking care of small LANs with an average of five 
client PCs. But this is a very remote place in South France, so most 
villages only have 512 kbps DSL. One major update for openoffice.org-*, 
and I have to wait the whole day for updating each machine (unless I scp 
-r /var/cache/yum from machine to machine, but that's another story).

I'm currently testing an "intermediate" solution: creating a local Yum 
repository. I have [base], which consists of all the 5.1 RPMS copied 
over from the DVD. Then [updates], which I'm currently rsyncing from a 
remote mirror. And I think I'll do something similar with [extra], which 
only leaves [rpmforge] (but I won't cache that :oD). Not a very 
satisfying solution, since for example I'm currently installing XFCE as 
only desktop environment, and I have nevertheless to download every 
GNOME- and KDE-related update.

A message to the developers: yum-proxy would be a much-needed addition 
to Yum, in my humble opinion. I don't have the technical skills to 
develop such a thing, but maybe one of you has (Daniel, do you read 
this? :oD)

I'm curious about your comments on this.

Cheers,

Niki
