Just to clarify on this point, the original TIGER import ran via the API on
a one second insert cycle. That was causing problems for other users so it
was backed off to a 3 second insert cycle.

The problem now is that we have even more users pressing for the resources
and thus I believe that while the process is slower than it might be if we
dumped straight to the OSM database the ability for users to control and
take ownership of the process via JOSM has a significant appeal to our
community based project. I'm sure that you will find many seasoned OSMers
who do not live in the USA will still be interested in "mapping" in the USA
in the same way some have been mapping cities in other countries using Y!
