Yep, as Eric mentioned, that is the purpose of this RFE ("want
filesystem-only quotas").
I imagine that this would be implemented as a quota against the space
"referenced" (as currently reported by 'zfs list', 'zfs get refer',
'df', etc; see the zfs(1m) manpage for details).

Yep, we're working on making more features work on "this and all
descendents". For example, the recently implemented 'zfs snapshot -r'
can create snapshots of a filesystem and all its descendents. This
feature will be part of Solaris 10 update 3. We're also working on 'zfs
send -r' (RFE 6421958).
