Please note that Monami6 was chartered to work on IPv6 only. But you  
are right, the same issue appears with IPv6.

Your comment is relevant to a multihoming scenario. It was one of the  
issue we raised in draft-montavont-mobileip-pb-statement-05 (issue  
described in 6.2.3, simultaneous location in home and foreign  
networks). However, I don't think it is a specific issue related to  
flow movement. It is a generic issue linked to Mobile IPv6 spec.
