Files created with vsphere on a seperate ZFS dataset are not visable from cli within FreeBSD itself

I did some testing today, and after reading and browsing the internet it 
is not possible to use a per machine zfs dataset with one single mount 
and export.
It looks like NFSv4 does support a single mount.

I go another route and use two mounts, one wich will be snapshotted 
daily and one less often.
This way i have two datasets that i can work with. But it would be 
really awesome if it did work.
It would give even more flexibility to the whole system.

Thanks all for your time..
