[CentOS] Something like apt-cacher for CentOS/RHEL?

Hi,

For some time I've fiddled with Debian and Ubuntu LTS. There's one 
really nice feature for local networks: apt-cacher, a package proxy for 
APT.

My company is in the remote South French countryside, and more often 
than not, schools and public libraries only have some very limited 
Internet access with relatively low bandwidth, which can make the 
updating process very tedious. A package cache comes in very handy in 
such situation.

Do you know if something like this exists for RPM-based distributions?

Cheers,

Niki
