The only reason I can see for sticking religiously with the 
upstream/CentOS base is to use the LiveCD as a tool to test hardware 
compatibility. IMHO that's a lost opportunity as others have noted and a 
LiveCD deserves to be so much more than just that. Besides, we all 
install additional drivers on our real systems when hardware isn't 
detected or supported by the base offering - just that's somewhat more 
difficult using a LiveCD which by it's nature is intended (in many users 
opinion) to be quick and easy to use, not more difficult. We will likely 
just lose that potential userbase to Ubuntu.

I appreciate this IS a difficult call as when you add functionality you 
also lose the ability to use it as a strict testing tool for out of the 
box distro compatibility. Is there any way we can have the best of both
