That's a pretty pessimistic view.

This would mean we are excluding some features, or some tagging
schemes, in some parts of the world due to disk space or processing
time but not in other parts of the world.  I'm sure we will never have
uniform tagging and uniform data quality everywhere but I still want
to aim at it.

For the record an import I've done had only this left/right - to/from
housenumber information, too, so I have an ugly python script here
ready to throw at this kind of data (after adapting to whatever the
input format is) and I would be happy to do the processing on my PC if
you decide to go this way.  The whole toolchain should still behave
reasonably for data size of TIGER (though obviously I didn't have that
much data)
