If there was serious community interest in this, I am sure the RIPE NCC could be persuaded to test this as part of the well-oiled de-bogonising machinery. this immediately provides automated measurements as well. It may take a little longer than sual to set up as we may want to ask all our de-bogonising peers whether they are OK with this just to be sure. Daniel PS: Personally I am not convinced that this space will ever become useful for global routing. But we won't know for sure until we have tried it. ----- End forwarded message -----
