If your current business model means that your business
cannot continue in an IPv6 world, then a competent
business manager will change that model. If the IPv6
address policy requires hosting providers to sell the
blades in their servers, and to SWIP a /48 per customer
end-site (i.e. blade) then they will do so. There is
precedent for this when IPv4 addressing policy drove
hosting providers to name-based virtual hosting.
I'm not terribly worried about situations like this
because I know the applicants can adjust their business
plans, and future business models, to work with the policy.
A while back on PPML I noted that RIPE had allocated
IPv6 space to several organizations with no IPv4 allocations.
Under the assumption that these were not existing IPv4
ISPs, I had a look into several of these organizations.
One of them was the IT function of a retail chain operating
in Germany, Poland and Turkey. If they could qualify as
an LIR by organizing their business with a separate
IT and network services function, then I think the rules
are less restrictive than most people think.
If you feel you should qualify as an LIR, then apply
for your /32. If you get rejected, asked for detailed
reasons why. If the reasons are due to misunderstanding
or a lack of information, then remedy the situation and
reapply. If the reasons have to do with your structure or
your plans, then change them and reapply. If you can't do
that then I would question whether you have a serious
intention to be an IPv6 service provider.

You know, the problem with those blade servers is that
they generate too much heat and use too much electricity
in one place. This increases HVAC costs and increase the
risk of power problems. It also creates a massive downside
during a power outage if you can't keep the HVAC running.
Much better to find a cheaper real-estate location where
you can rent rack positions rather than blades. Customers
can put whatever they want in their rack positions. Maybe
it's a WLAN proxy relay station or their own blade server.
You can't know how many devices will be at the rack position
therefore you should allocate them a /48. After all, you
are a hotel. You rent rooms, you don't police what goes on
inside the room.

It has also been suggested that the simple presence of
multihoming should be sufficient justification for PI space.

People have done creative things with tunnels in the past.
The widespread existence of MPLS backbones makes that
even easier. You will always be able to find one situation
that simply will not fit a given policy. Regardless, we still
need to have some reasonable policy that creates a level
playing field, does not unecessarily restrain trade, and
creates possibilities that smart entrepreneurs can exploit
to expand the network.
