Yes

The source dataset from the government isn't likely to go anywhere so 
I'm not too concerned about it getting lost.

So far the import scripts I've been using are in python.

For the geobase roads I am using a program called RoadMatcher that is a 
plugin to JUMP for detecting roads in that are likely to already be in OSM. 
I then import the geobase roads  and tag each way with the uuid 
(geobae:uuid) that mostly identifies the source road segment. I exclude
the roads flaged as already being in OSM.

Once I have the road network dealt with I (or another eager volunteer) can 
create the address nodes+interpolation ways using some of the methods 
discussed on the thread.  Connecting the interpolation ways to the 
previously imported nodes with a realtion shouldn't be hard.  I know the 
uuid that the address applies to. I can get the way_id by searching a local 
copy of the OSM database for that geobase:uuid.  A script can then 
get/edit/upload the existing way though the API.

The script we are using for importing the base roadnetwork is available 
http://svn.openstreetmap.org/applications/utils/import/geobase2osm/

I am currently working on another script to fix some issues in the some of 
the roads imported so far (a bug prevented some intersections from sharing a 
node). This will use the local lookup, query ,edit technique I discussed 
above.
