a very true point in one way but that is again as I see it, we're still 
thinking IPv4 when talking IPv6.

Why do they need multihoming and PI? They don't trust the ISP and vendors 
to deliver them uptime and freedom... isn't this a problem the ISP and 
vendors should try to solve? Of course, the idea of easy renumbering was 
suppose to solve this but again, we're thinking IPv4 so it's not easy to 
understand.

Again, we don't need PI space and multihoming, what we need are a way to 
give the users and GOOD connectivity (uptime, speed etc) and make it easy 
for them to switch providers as they see fit.

for several years this discussion have been going on, still no real 
solution. IPv6 give us the freedom todo ALOT of things, USE those 
possibilities, if we have to change how IP are done, some TCP headers etc, 
then do it... propose a good idea and prove it. That could give us 
multihoming. Actually there is a master thesis about howto create 
connectivity for TCP session even if one of the links went down, the 
session just used another IP (1)... the user don't notice anything 
either and it have zero problem working with standard tcp-stacks since it 
use the extended header of IPv6.

That's just ONE of many possible ways...
