Joe, all, Just to clarify something Fernando purposely missed in his call for action: All operations on the packets discussed in SPRING WG are happening NOT on the original (end to end) packet header. They are all defined to happen within new imposed outer encapsulated header (IPv6 in IPv6 to be precise). So original packet just get's tunneled between various points of the network. Last time I checked that operation is allowed by RFC2473. Its subtle detail, but fundamental one to this entire context/discussion. Kind regards, R.
