Thank you!

Err... 
I suppose things are even more complicated:
1. IMHO, "rolling" means "you don't have to change anything to upgrade", so by my dictionary, both SL's "4x" and CentOS' "4" are "rolling", as they map to the latest "4.5" etc.
2. Maybe CentOS' "FastTrack" repository
is something like SL's "rolling"?! Aren't both of them something "available before it's really available"?
3. "Beta" is really beta... and nobody wants to run such stuff...

Thank you one more time,
R-C
