OpenSource interface for ZFS like webcvs?

[Rudy]

Before I reinvent the wheel, is there an opensource zfs browser?  
Something that shows snapshots, usage, quotas, etc. and allows snapshot 
cloning, cloning, snapshot deleting, etc?

I am loving ZFS and the CLI, but want to let some CLI challenged people 
manage snapshots.

Thanks,
Rudy
