My WG having been a victim of a long debate on router alert, I believe 
there is value in documenting if or when RAO should or should not be 
used. Yet, there are already several RFCs that discuss/present RAO 
(2113, 2711, 5350). I have thought about the RAO lately and how to go 
forward, and it might make sense to merge these existing specs together, 
add recent views on RAO, and obsolete the previous RFCs.

I will arrive too late on Monday to take part in the int are meeting and 
hear the discussion, unless it would happen as the last item on the agenda.

cheers,
Jukka
