I haven't read the 80+ posts in entirety, so these might have been mentioned, but three ideas that could work:

1) RHEL for the security admin, where it goes in depth on hardening RHEL, intrusion detection and intrusion prevention.

2) RHEL for storage admins, software/hardware RAID, volume management and snapshots, NFS/CIFS network file systems, FCoE/iSCSI shared block devices.

3) RHEL for the network admin, firewalls, routers, bridges, traffic shaping, route load balancing, and network traffic monitoring.

I think these can be expanded out some more, and while there might be some overlap they should be each more targeted then a broad course.
