OS X/FreeBSD shared zfs partition

Wow... I really didn't expect that to work! Well, it 'kind of worked'.
Here's what I got:
I did 'zpool import' and got the usual 'ZFS is experimental in FreeBSD, ZFS
filesystem version 6' and it said something like 'you can import pools by
name' (sorry - i missed the exact message). Then I did 'zfs lilst' and tank
was listed, but not tank/jwhendy.
Then I did 'zfs mount tank/jwhendy' and got:
'Mismatched versions: Filesystem is version 2 on-disk format, which is
incompatible with this software version 1! You can force mounting with -f'
I did 'zfs mount -f tank/jwhendy' and it said 'Cannot mount 'tank/jwhendy':
Operation not supported', but zfs list shows:
NAME USED AVAIL REFER MOUNTPOINT
tank 11.4G 27.2G 390K /tank
tank/jwhendy 11.4G 27.2G 11.4G /tank/jwhendy
So... it appears it mounted? when I cd /tank/jwhendy, though, all that is in
the folder is a file called .autodiskmounted, which I assume is used by OS
I think we've made some progress... any way to go the whole way? Can I
upgrade the zfs version in FreeBSD since it complains about the mismatched
software versions? Just a thought.
