patch management

Hey,

Is there a centralized patch management solution that works with RHN? The Windows admins have a patch tool that allows them to approve each patch and push them out to groups of servers. I would like to have this functionality for our Linux servers.

We have a mismash of servers from AS3 to RHEL 6.3. Any version of Redhat still supported on RHN would need to be managed by this servers.

I am looking at Satellite. From what I have read this may not be the solution we need.
