Ahh, it was the lack of mount that caught me! Thanks Darren.
It is documented in the zfs(1M) man page:
Permissions are generally the ability to use a ZFS subcom-
mand or change a ZFS property. The following permissions are
available:

snapshot subcommand Must also have the 'mount' ability.
I've read through the manpage but have not managed to get the correct
set of permissions for it to work as a normal user (so far).
What did you try ?
What release of OpenSolaris are you running ?
snv 118. I blame being tired and not trying enough options! I was
trying to do it with just snapshot and destroy expecting something like
a snapshot didn't need to be mounted for some reason.
Thanks for the clarification. Next time I think I'll also consult the
administration guide as well as the manpage though I guess an explicit
example for the snapshot delegation wouldn't go astray in the manpage.
Like the one that is already there ?
Example 18 Delegating ZFS Administration Permissions on a
ZFS Dataset
The following example shows how to set permissions so that
user cindys can create, destroy, mount, and take snapshots
# # zfs allow cindys create,destroy,mount,snapshot tank/cindys
