Mapping? How do you mean. I or one would be extremely hesitant to even 
consider federated mapping, if only because the end user will have 
severe trouble keeping track of all the different networks. This is 
precisely why E164 exists. Keep your numberingspace consistent, 
regardless of the dialling network.

'More fair' is unfortunately not the key issue for a publicly used 
federation. In general, customers rely on the fact that if they dial a 
number it will consistently connect to the proper destination. If this 
is negatively impacted in any way, my consideration as a telco is not 
wether or not the blacklist is fair to the receiving end. I only have my 
customers to answer to, and I want the misbehaving party disconnected 
immediately.

This is a faulty observation. It is absolutely possible to connect to 
multiple nodes and perform the discovery over multiple nodes in order to 
improve resilience of the number discovery function. However, because 
there is a practical limit (increasing post dial delay) in the amount of 
hops traversed during discovery, it makes sense (optimisation-wise) to 
connect at a semi-geographic oriented Tier1/Tier2/Tier3 structure. At 
two to five nodes, probably.

Your security ideas are obviously possible, but I don't really see the 
point in that. Connecting to more than, say, 10 nodes doesn't really 
make sense, and adding/removing nodes is not a day-to-day task. With 
that in mind, manual connection with individual keys should not be that 
big an issue. To reflect: Do you do BGP peering with anyone? Would you 
want anyone (without scrutiny!) to be able to broadcast AS-numbers into 
your routing table?
