The other option was to base it on importing shape files, and this perl
script:
http://wiki.openstreetmap.org/index.php/Shapefile_upload_script

Martin Spott said he had TIGER and lots of other free data that we can
import already converted to Shapefiles (or easily convertible to
shapefiles). Also TIGER itself is moving entirely to Shapefiles next year.

If anyone knows a good shapefile library in Python, we could easily port
the above script - there's not much to it.

Alternatively, we could import the shapefiles into PostGIS, and have the
python talk to that. While this may sound over the top, I think it would
be useful to have a spatially indexed database of the current data
available for finding if there is any nearby data that should be merged
with (if we are adding a point very close to a point we have just
added), updated (if it's a point we added on the last run) or left alone
(if it is pre-existing OSM data).
