The part I like about ZFS is the way you can dynamically allocate
physical volume space to any logical volume (aka: filesystem) at any
time.

Nothing else does that as far as I know. All you get is LVM2, EVMS,
or "mdraid" none of which can dynamically resize the volume and
underlying filesystem on the fly, and EASILY. resizing an ext partition
is imo, too hard, and you _can't_ shrink an XFS filesyste. Function isn't
supported.

how much of this is a limitation of the technology (like the inability to shrink XFS) and how much is just a need for better userspace tools (like easily being able to resize extX)

don't mix one with the other.
