As tends to happen, right after sending this I located a guide which 
apparently doesn't make the assumptions in the first documentation link 
I sent, specifically the section headed "Containers Residing on an 
Oracle Solaris ZFS Filesystem":

http://developers.sun.com/solaris/docs/howto_movesolariscontainer_051410-1.pdf

Will work thought this and shout if I have questions...
