=> ok.

=> How do you expect the 2 ARs to talk to each other
if they don't have a common IP version? If they do
then sure CTP will work but nothing else will, like: 
- connectivity (existing connections) of the MN using its v6 address? 
- Mobile IPv6 signalling ? 
This is one of the motivations for the dual stack MIP
work that we discussed on MIP6 and v6ops list some time
ago.
