Hello Ray,

I am a .net developer and allready made my own little parser, but it 
stranded when I got busy with more important matters.

I would love to help you and I agree that placing it in a separate 
branch of the OSM repository would be best.

You say that it imports into SQL databases, do you mean SQL server or 
any SQL?

Are you aware of msSQLSpatial, a spatial extension that is available for 
SQL Server 2005 (Express and others)? It is OGC compliant and has almost 
the same structure as postGIS!

You can use my eyes!

Kind regards,

Milo van der Linden
