If they are happy we are happy, but once imported data in OSM never
really goes away because it is of course in the history so anything we
add to the main OSM database is added forever.

I'm wondering if the first step might be to import the data to a
seperate database so that we can render an overlay on to the existing
OSM data without populating the main database.  We could then get the
overlay as correct as possible and give other editors the ability to
double check it before it became final.
