[ppml] Just say *NO* to PI space -- or how to make it lessdestructive

[Jason Schiller (schiller@uu.net)]

David,

The problem is the routing economy as Geoff points out...  Sure, if you
have your own space, and you purchase transit services from a provider,
then they will most likely route your space.

But what about all the other transit providers in the DFZ?  are you also
paying them to carry your prefix as well?  What about all of their down
stream customers that carry a full routing table, are you going to pay
them as well to cary your prefix? 

If there are a very limited number of routing slots in a provider's
routing table then the providers are likely to desire to reserve these
slots for paying customers.
