Yes, I meant scripts that generated the OSM files. I converted my
county's data (which has more attributes and is more recent than
TIGER, but feeds into it) to OSM files, which I documented here (not
mentioned is the "glomming" I did to join segments with identical
attributes, or the simplifying I did):
http://wiki.openstreetmap.org/wiki/Fairfax_County,_Virginia/Roads

and have been using it with the manual conflation process I described here:

It does take quite some practice to do correctly and efficiently.
