[From another list. Note lack of cross-posting.]

I suggest to the chair(s) to ask this question at the 
upcoming WG meeting.

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.

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.
