I think I have seen close to 40 presentations that all would solve the 
multihoming problem one way or the other, or at least parts of it.

It's possible for a small ISP to get several blocks from their 
upstream, route them inside their network and assign each of their 
customers with an address out of each of those blocks. Does it scale? 
Nope. Can it handle failures in the upstream? No. Etc.

There are several of the proposals in multi6 that have never received 
comments, nor support of any kind.

Your document does not address the criterias for being classified in a 
particular category. It does not address what would happen if an ISP 
grow, get's split/divided. It does not address what the financial 
models for transit would be. It does not address the non-balance of 
local vs global traffic coverage. It does not take into account the 
current peering economics of the Internet. So it's really hard to say 
anything regarding it.

Which is a limiting factor that I think you will that customers will 
find unacceptable.

Having to renumber when chaining ISPs is not to discourage _change_ of 
ISP. It's to discourage signing up with that ISP in the first place.

In what way?

I am not following this. In what way would the RIRs get more "power"? 
The policies of the RIRs is set by the RIR community. We are having a 
lot more routing entries today than we need to, and people seems to 
think it is a good idea. Actually it is today used to implement 
policies that follow requirements set by users to their ISPs. Users 
that pay to get that policy.
