For the Canadian GeoBase road import I've been using a plugin to JUMP called 
RoadMatcher[1] to that detects common roads between two datasets. I've then

A few more details at:

For land-use you could probably write some SQL queries that run against a 
osm2pgsql instance that find which of your land-use polygons don't intersect 
with existing osm land-use tagged areas.


I don't mind joining a mailing list for the data import working group, but I 
have enough on my plate with the various Canadian datasets that I won't be 
able to provide assistance scripting or importing to others for sometime. 
I'm not sure if I'll be able to make weekly conference calls either.
