nordu.net

The reason being that we don't actually own an DNS names or anything at 
all (trademark, etc) related to the northernlight name AFAIK.

Depends on the level of hardcode :-)

But yes, topology configuration is a bit of mess currently. It might 
improve, but we did come up with a model that is quite compliciated and 
largely ignores that there are people out there which have not been 
following the NSI standard track that have to configure the NSA.

I don't think we will ever get something that is completely consistent and 
correct. The code for topology aggregation and path finding will have to 
do a lot of sanity checking and be fairly resilient in order to work.
