Hey, I haven't had a chance to look at this yet, but I just opened up the
input file in a text editor and saw:
Copyright=THIS MAP CANNOT BE SOLD
I think this is incompatible with our license (commercial use is okay). Is
the author/maintainer that gave you permission aware of this?

The Nod[1...] bits define the routing nodes--i.e., which points in the Data0
linestring connect to other ways. The first and last points of a way always
have these, and more if there are any intersecting points in the middle. For
this map, though, it's probably safe to say if  the points are at the same
spot, they're routing nodes (i.e., it should be represented by only one node
in OSM, shared between the intersecting ways).
