ZFS delegated administration

ZFS makes practically reasonable to give each user a file system. Now what if you want to delegate some ZFS administrative task to that user so for example he/she will be able to create sub-filesystems? It's been integrated into b70.
Check this blog entry for more examples.

Separate Intent Log for ZFS

Ability to put ZIL on a separate device was integrated into b68. So ff you care about ZFS performance see this blog entry.

I wonder if Sun is going to sell x4500 with some kind of nvram or SSD...
