I have a suggestion that may work for you, for the time being..
On our shared servers, we have a service called Shadow Copy. Here is a link to a wikipedia article discussing Shadow Copy.
http://en.wikipedia.org/wiki/Shadow_CopyIm not entirely sure how it works, and instead of describing it incorrectly, you should probably just read the article :-).
But near as I can tell, it uses the System Restore files of Windows to give you, the admin, a Previous Versions tab in the properties of a file or folder. Its really nifty, and admittedly, it does not replace a backup UI, but until one is deployed, its a pretty nice interface for replacing one or two files or folders. I know we use Shadow Copy on our servers, and its even easier than going to CommVault most the time.
So, as Derek said, Commvault is definitely becoming more versatile, and it sounds like we are exploring a UI for restores, but for the time being, I really hope that shadow copies can do some good for you guys.

I think its worth noting also that Shadow Copy does not replace Dedicated Backups, as Dedicated Backups are off server, and Shadow Copy just runs off of the same 'backups' as System Restore.
