ZFS mount points and zones

Question

folks,
a little history, we've been running cluster 3.2.x with failover zones (using the containers data service) where the zoneroot is installed on a failover zpool (using HAStoragePlus). it's worked ok but could be better with the real problems surrounding lack of agents that work in this config (we're mostly an oracle shop). we've been using the joost manifests inside the zones which are ok and have worked but we wouldn't mind giving the oracle data services a go - and the more than a little painful patching processes in the current setup...
we're started to look at failover applications amongst zones on the nodes, so we'd have something like node1:zone and node2:zone as potentials and the apps failing between them on 'node' failure and switchover. this way we'd actually be able to use the agents for oracle (DB, AS and EBS).
with the current cluster we create various ZFS volumes within the pool (such as oradata) and through the zone boot resource have it mounted where we want inside the zone (in this case $ORACLE_BASE/oradata) with the global zone having the mount point of /export/zfs/<instance>/oradata.
is there a way of achieving something like this with failover apps inside static zones? i know we can set the volume mountpoint to be what we want but we rather like having the various oracle zones all having a similar install (/app/oracle etc).
we haven't looked at zone clusters at this stage if for no other reason than time....
or is there a better way?
thanks muchly,
nelson
