While this may or may not be true, the RIPE NCC is in no possition to
guarantee routability likeliness. Today filtering is done on prefix
length for obvious reasons - if the policy were to change to allow big
blocks for some reason other than the need for the volume of addresses - I
am quite shure we will se some other filtering coming up.

From the discussions over the last years on this topic I see that the sole
need for PI space is entities who want to be multi homed, thus beeing
independent of a single provider.

Often its not a matter of distrust - its a matter of the up stream
dictating your business practices. Couple years ago I had a phone call
from one of the Scandinavian regulators - he had gotten the impression
from small ISPs in his country that it was mandatory to use address space
from the upstream in order to buy transit from that particular upstream -
thus locking the ISP to a particular upstream.

While it may be some degree of trivial to renumber the internal
infrastructure of an ISP - it is close to impossible to renumber your
customers - if you do that you gvie your customers an intencive to
reevaluate their service provider, which is not something you want to do
to all your customers at once.

One way to solve this is to introduce a one time service fee for the
initial block - I seem to remember APNIC is doing something like this.

How real is this case theese days ?
