Can't we all just drop using the word multihoming and IPv6 PI? 
They all reflect back to how thing was done with IPv4 and those ways are 
doomed to fail with IPv6 simply due to the size of the IP space.


Last I checked around there were some promissing new proposal on the 
way for how to solve this very basic problem. And in the meantime, drop 
the thought about multihoming and PI space, start to think about other 
ways to use the possibility IPv6 give us. Just to mention maybe the 
biggest advantage, we have that extended header part of IPv6, it give us 
endless possibilities.



and yes I do have some idea about how it can be done but no one really 
bother to consider geo-based IP's either so... :) Not to forget it quite 
likely will undermine the entire business case for how ISP's today 
operate.
