for step 8, the correct word is MERGE (not purge).
Meaning where we can merge our address book with hotmail when we
import a new csv file, the system checks for similar values; like
names; like address; like phone number.
So in this case; its the long/lat coordinates that it would check for.
In the case where the OSM (or import) is WAY OFF, then it would check
for the same 'name or other OSM tag' to decide if its a match. -but
coodinates get checked 1st.
-unfortunatly, the only program that can do this is ArchGIS (i think)
-is there any opensource equivelant that can do this?
ps on reply, no need to cc talk list, as this is getting off topic
