I think Fred is describing reality for those of us that have global
networks. Maybe you have a point on the /64's; that could be an option.
But sorry, no global corporation is going to accept a single ISP
solution as currently dictated; not one of us would survive trying to
explain this to our Boards. That is reality whether the routing works
or not!! And it is the crux of whether v6 can advance or not.

Um... generally, the company should be giving /64s to the employees,
etc., not /48s. Every end user with a DSL line, generally, should also
getting a /64 unless they have need of multiple networks, in which case,
a /48 would be justified.

Not necessarily, however, this example is _NOT_ the example that 2005-1
is targeted for. This example could be an LIR. Now, if the company
to treat each site as a separate ORG, then, those sites might,
be eligible for /48s under 2005-1.

If you're going to be an LIR, it comes with the responsibility for
building a backbone sufficient to meet your Intradomain connectivity
needs. If your dealing with multiple organizations that are diversly
connected, then, topologically they are many small organizations,
not one large one.
If it wasn't crypto-signed, it probably didn't come from me.
