Dear Kurtis;

There is no guarantee that an IPv4 /24 will get routed either, nor the
/23's assigned by 2002-3. (I see this as basically the  IPv6 analogue of  2002-3.)

However, having officially assigned address block does certainly help.

What the current proposal really does is set a new expectation of
IPv6 /56's as becoming standard. I would feel more comfortable hearing from a critical mass of IPv6
vendors or SP's that this would not cause problems (it shouldn't, of course, but...). Unless it
does, I see no reason not to support this.

I do not know, but  I suspect that he was trying to include the many sites that
get IPv6 through some sort of quasi-permanent tunnel, which  seems reasonable to me,
at least at this state of deployment. This is a tricky  issue (one could always order
2 T1's for a few months and get an ASN, all to get a 2002-3 address block, and 
then remove them, but that seems like a lot of work and cash
for a v4 /23 if you don't really need it. Now, if I can just set up two tunnels to somewhere, maybe
for free, and then take them down once I get a /48, maybe that is not a high enough barrier to

Here is a suggestion : tunnels (of any sort) should count for multi-homing if you are already IPv4
multi-homed or have IPv4 address blocks assigned to you (though 2002-3 or otherwise), but otherwise
you need direct IPv6 connections. (I.e., if you  are .v4 multihomed, you get a certain presumption
of being truly .v6 multihomed.)
