But regardless of where the allocations come from, there will still be lots 
of allocations that cannot be summarized that otherwise could be summarized.

I am not intimately familiar with RIPEs or APNICs policies.  However, 
according to RIPE-269 you are not correct:

IPv4 CIDR block 	Default RIPE NCC	    Smallest RIPE NCC
			   Allocation	    	Allocation / Assignment
	 62/8 			/19 			/19
	 80/8 	 		/20 			/20
	 81/8 			/20 			/20
         82/8			/20			/20
	193/8 			/19 			/29
	194/8 			/19 			/29
	195/8 			/19 			/29
	212/8 			/19 			/19
	213/8 			/19 			/19
	217/8 			/20 			/20

APNIC does have a policy for multi-homing though I am not familiar with it. 
I am sure somebody else here can provide more accurate information.

Well, routers are getting faster and smarter, but you are assuming that 
routing table growth and routing table computation increase linearly with 
respect to one another.  I do not know enough about route computation 
algorithms to say one way or another.

But can multihomed joe end user afford the latest and greatest 6 and 7 
figure router?  Many people are running low-end or old routers that are 
being pushed to the limit.  What about them?

Just so we're all on the same page, I am all for doing what is best for the 
entire Internet.  I realize I have mainly been arguing routing table issues 
against reducing the minimum size, but that is mainly because of the fact 
that there are very few people arguing those points, and I feel it is 
important for both sides of an argument to be presented.
