In other words, is there a way to specify the rights of the
owner of a filesystem rather than the individual - eg, delayed
evaluation of the owner?
I think you're asking for the -c "Creator" flag. This allows
permissions (eg, to take snapshots) to be granted to whoever creates
the
filesystem. The above example shows how this might be done.

Actually, I think I mean owner.
I want root to create a new filesystem for a new user under
the /export/home filesystem, but then have that user get the
right privs via inheritance rather than requiring root to run
a set of zfs commands.
In that case, how should the system determine who the "owner" is? We
toyed with the idea of figuring out the user based on the last component
of the filesystem name, but that seemed too tricky, at least for the
first version.
FYI, here is how you can do it with an additional zfs command:
# zfs create tank/home/barts
# zfs allow barts create,snapshot,... tank/home/barts
--matt
Owner of the top level directory is the owner of the filesystem?
When a file system is created the owner/group of the root of the file
system are set to the user/group of the user executing the zfs create
command. That is also the user that all of the initial create time
permissions are set to.
