Yes, the purpose is to use a ZFS-based storage on multiple nodes
without iscsi. I don't know if Proxmox VE LXC is going to work, but
"normal" ZFS filesystems via NFS work on "normal" LXC on Jessie. I'm
running a few LXC containers on my Pi this way.

ZFS can share filesystems automatically via NFS. You only need to have
one 'dummy' entry in /etc/exports on Debian to get the NFS server
started. Afterwards it'll automatically share over the NFS server with
the option sharenfs. On Solaris, you will not have a problem at all.
Just use sharenfs on ZFS and you're good to go.
