Zones as SMF services, as detailed in my article on OI Wiki http://wiki.openindiana.org/oi/Zones+as+SMF+services
Currently this includes all the code defined as part of the SMF manifests, so nothing to install except registration of the two XMLs. See Wiki article for more details, or consult the command-line help.
The most trivial setup automation with
cd bin
./zoneadm-smf install
should register the needed services and wrap all your existing zones into individual services grouped as svc:/system/zone-group:default
Hope this helps, Jim Klimov
