Alex, I really really don't see the need for what the draft calls "symmetric bi-directional tunnels". While such constructs might be used in the traffic engineering context the TE context comes with a control protocol (MPLS) for setting up the explicit paths and recovering from failure. Getting MPLS to control IPv6-in-IPv6 tunnels would be a huge exercise of very questionable value. Thus my personal opinion is that the draft should only specify "regular" bi-directional tunnels.
