Tigris's Current - Up2date server

[Johan Booysen]

Hi,
 
do any of you use, or have used in the past, Tigris's open source
up2date server called "Current" (http://current.tigris.org
<http://current.tigris.org> )?
 
I'm looking for a way to implement an internal server that synchronises
rpm packages with RHN, download the packages, and then serve as a local
source  (for RHEL3 servers)  so that I can update those other internal
servers by pointing them at the internal repository.
 
Current seems to be able to do this.
 
Or does anyone have experience of any possible alternatives that I can
look into?
 
Thanks very much.
 
Johan
