Perhaps we are having a problem caused by your use of the term "address", which does not seem (see below) to mean what I usually take it to mean. (I really wish we could just stop using the term "address", because it means so many different things to different people...) To me, although there are apparently many different definitions for "address", they almost all share one common attribute: that they are used by the path-computation process. So in saying something is an "address", one is implicitly saying 'this will be injected into the routing'. Furthermore, "PI" means 'does not contain any information on location', i.e. it not local to one particular scope, i.e. its scope (i.e. the part of the network over which it must be advertised) is global. So now we have "PI address" meaning 'something which has to be injected into the routing, and must be visible over a global scope'. So how is it that these 10 million (or however many companies it is) can all have "PI address[es]"? I am sort of forced to the conclusion that what you mean by the phrase "PI address" is something different, perhaps some sort of identifier which is _not_ injected into the routing?
