=> I don't think so. There is a difference in existing 
standards (2461) and implementations between the 2 cases. 
A multiaddressed node with a single interface assumes 
that any address can be used as a source address with any
default router. This is clearly not a good assumption 
for multi-interfaced (multihomed) nodes
