Come one, others here also *WERE* there back in the classful times, and 
screamed "we need a change!!" when their Cisco 3640s hit the end of 
their usefulnes - heck, even i supported the shim6 (or similiar) 
development.
It's not only you that recognized that problem and started to fear the 
possible outcome, but you haven't realized that times are changing yet.
I don't see any routing table problem for the forseeable future, you 
have plenty of time to come up with a new, scalable solution and start 
to deploy it.

I still *DO* support *ANYTHING* that keeps the global internet routing 
tables small and shiny, i really do, but not to that extent that i 
render the Internet/IPv6 completely useless and "racist" by not allowing 
IPv6 provider independence.
	
This is real-life internet free market economy nowerdays, deal with it.

- I will explain to customers that renumbering is not a big deal
   if it really isn't in their cases
- I will explain to customers that there are other possibilities
   for multihoming right now and see if that works for them first
- I will use any possible other new solution to the problem ("shim6")
   if it fits the customers needs in the future
- I will urge any customer to become a RIR member and explain
   all advantages of that to them
- I will not solicit the usage of PI vs. PA or anything
- I will not pass any PI requests or similar from customers if i'm
   not convinced that they really need it and know what they do

but i will NOT deny anyone a routing-table slot just because of their 
size or monetary issues.

So, please, continue with your quest for a better solution, i will 
appreciate it and bring it to use whereever applicable.

P.S.: Anyone got any recent numbers about the percentage of PI 
announcements in the table vs. PA announcements + deaggregates?
