Well, you don't need addresses for clients, just for content... From the architecture page at 
http://named-data.net/project/archoverview/:

"Note that neither Interest nor Data packets carry any host or interface addresses (such as IP addresses); Interest 
packets are routed towards data producers based on the names carried in the Interest packets, and Data packets are 
returned based on the state information set up by the Interests at each router hop."

So it's basically suggesting a NAT-like table in every single router. And we all know how well NAT boxes scale...
