I can think of two organisations which could probably take care of a 
good chunk of the problem, if people were prepared to leave it up to 
them. The routing system is already largely dependent on the 
interoperability of bugs produced by these people, and so arguably no 
additional trust would be required.

One organisation has a name starting with "j", and the other starts 
with "c".
