I have to agree with Frederik on this. With the NWB you mention, it's 
likely the vast majority of it will not be relevant to NL coverage, 
since we already have had a mass import of AND data. Why should we 
'pollute' the OSM db with data that's not going to be used on a large scale.

I'd too rather see such a source of data on a separate layer/db, through 
WMS for instance, so that we can compare, and (like Gervase puts it) 
"merge down" what we want.
