OK, so you're looking for fast re-route, and that primarily for  
servers. I said there was a case for PI, and that is one summarization  
of the case.

That doesn't mean that all sites everywhere should have PI addresses.  
How many servers are in hosting facilities? It means that the servers  
need them.
