Brian,

You are correct that the data is not "large" in terms of current systems 
or database capacities.  Despite the size, though, it's not static and 
it's difficult to maintain in every switch in the network.  The carriers 
don't want to do that anymore.  See the mails from Paul Rosbotham.  He's 
an expert in the field of maintaining number plan information.

IMHO, however, a "routing protocol" type system for distributing such 
information between devices is immense overkill.  It would easily morph 
into something at least two orders of magnitude more complicated than a 
DNS-based system, for little additional gain.
