Proxmox / ZFS / Single-box solution

Given all the awesome features of ZFS (and the awful zfs-on-linux speed/features/etc), it's a pity there's no way at present to get Proxmox running on FreeBSD-based distro (where ZFS v28 is supported)... From what I can see you, can do openVZ and KVM on FreeBSD 9.x.. (however FreeBSD uses jails natively), and of course FreeBSD supports ZFS, so it seems like the perfect framework..

is there any other way I'm not thinking of to single-box ZFS / OpenVZ and KVM?

{EDIT: Found the zfs-on-proxmox link - can't get dkms happy, but at least someone else is trying it... -- http://pve.proxmox.com/wiki/ZFS)
