[Centos] RHN-like system for CentOS?

[tengel@xxxxxxxxx (Troy Engel)]

Team,

Is anyone aware of a Red Hat Network alike system of server package 
update status that could be adapted for CentOS3? I'm not interested in 
the complete management aspect (channels, scheduling remote updates, 
etc) but merely the ability to see your list of systems and determine 
which are out of date with XXX packages. If you happen to manage a 
large-ish number of RHES3 systems, you know what a boon this is. ;)

Ideas? Thx,
-te
