Well, for the adventurous, there may be a possibility by making several slices in one partition. Certainly one can use the same disk for different pools - the problem is coercing the installer into that, but if Hans plans an install elsewhere (e.g. a VM) and zfs send or rsync to bring it over to physical disk - this bit is solved. Loaders and chaining is another adventure. Might also try VirtualBox installed in the first OS with a VM for second to which you delegated the other slice/partition.

Also, I think several MBR/GRUB partitions can be used de-facto (e.g. when you create a zpool manually with cxtydzpn vdev addressing), even if tools do not offer support for it.

IMHO, forcing a zfs v28 pool and coexisting in BEs on same slice and managing the loaders somehow would be easier ;)

And VMs yet easier. VirtualBox runs on either.
