[CentOS] Enterprise Package Tracker

Is there a utility such as rpmfind that exists for enterprise
rpms? One could locate rpms from various repos e.g. 

- Centos base, extras, plus
- EPEL
- RPMForge
- KBS repos

Due to the requirement of a subscription, upstream or others
like Oracle Unbreakable linux couldn't be listed.
