Ok. For this to work you will most likely need to drop nodes which
shouldn't be MPR from the neighbor set if you want to be RFC
compliant. That shouldn't cause any problems, but it would be nice
if the information about the full neighbor set was kept around 
somehow - we use this a lot for link planning (As we use the 
information from topology flooding for our map.)

Yes, that would be extremely useful. Depending on how far you want
to go it might be difficult to implement for a link state protocol 
though ...

May I ask where such discussions are taking place?
