On the other hand, if one is going to have a network in which all resources are publicly available and unambiguous without prior negotiations between each client and server and in which one doesn't want to allow the time and resources for a post-query disambiguation process (which is exactly what we do to identify the desired "Joe Smith" from that pool) then identifiers must be unique. Not overlapping name spaces, or fragments of a name space that the client gets to pull together based on its own choice algorithms, or a fraction of the aggregate name space chosen on the basis of "least bad" or "most complete" service by a name-vendor, but _unique_ and comprehensive.
PNRP attempts to ensure numeric identifiers are unique, where names freely associate without concerns of conflict. The basic goal is to overcome limitations of DNS using more elaborate structures. This extra information might provide a sequence of IPv4 and IPv6 addresses needed to navigate through various gateways and NATS. The end-points of this navigation are introduced through "groups" where each member of the group retains other member's certificates as a means to verifying and differentiate possible naming overlaps. This does not require unique names , but rather numbers based upon similar concepts developed by the T10 group for CAS.
This different (and some what scary strategy) allows for the ideal end-to-end networking paradigm. Each and every network node is visible to the Internet for true end-to-end communication. Firewalls designed to shore up flaws often found with complexity created by ever growing features are bypassed. The demand for (anti-productive) gaming and effortless collaboration tools are designed to segment networks into "groups." This demand may soon offer a (proprietary) alternative to DNS, where navigation still takes place at the browser using this "different" type of namespace. As noted in the promotional literature, there are no copyrights on numbers.
