IPv6 Routing table will be bloated?

what's the problem anyway

with 32bit ASN's there should be enough AS namespace to give everyone that 
wants to multihome their ipv6/ipv4 PI their own AS number...

should pretty much be the de-facto standard (unless ofcourse you want to 
tie your customers to your internet-provider-activities by making it hard 
to leave)

maybe we should have made AS numbers 64 bit as well... so there would be 
one for every /64 end user

as for the rest of it: get routers with more ram (i don't want to hear any 
"my border routers have less than 8GB of ram") arguments, that stuff is 
-old-, it's got gray hair and a beard and belongs in a museum, not on the 

The internet will grow, you can't expect it to grow less fast or to 
"aggregate" routes just because your technically outdated stuff doesn't 
have enough ram to handle the growing route table size. (preferably 
offset-based rather than with a sort/lookup mechanism)

if a customer has a /64 and wants to announce that /64 himself, i see no 
reason not to give it to them, especially not if hte only reason would be 
that some people run still routers that have less ram than my eeepc.
(and some suppliers still think that's "OK" to sell)
