would it not be a good idea to NOT disclosure service versions?
https://bugzilla.redhat.com/show_bug.cgi?id=718133
you will more and more have the "problem" of 3rd party
security scans to your servers and currently in the case
of openssh the only solution is to tkae the F16-src-rpm
and rebuild it for your F15 machines

however - why do we spit the current running versions to everyone?
