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.
Cisco is already a member of ARIN. If anyone out there buys Juniper
routers, perhaps you might suggest that they also join ARIN and work
together with Cisco and the network operators to move this forward.
