Well, I was really in favour of ULA-C but now given some time and after 
listning to all of the arguments, and maybe most important I realized one 
huge thing that ULA-C maybe can't provide, DNS, which leave it useless for 
our usage.

Without reverse DNS possibility ULA-C is useless.

On the other hand, why do we need PI? What we need is a policy that make 
sure those that could gain from ULA-C can get public routable IP space, 
and then they can themself decide if they want to route it or not. It's 
possible and upto them.


If we have to call it PI then so be it... I really dislike the name but I 
can live with it.
