Steve,

I totally agree to your opinion. We can have a standard framework and we 
may call it "OSgeo international geocoding framework", not "geocoder".

Everybody would love concept of GDAL/OGR, however, geocoder will have 
deferent story.

In my experience of working for a U.S. based GIS company which has global 
operations, an international geocoder was always requested by customers. 
The company developed geocoders of U.S., Canada, England, Western part of 
Europe and Australia. However, they are not really unified. Even they have 
similar address systems, the U.S. engine couldn't handle other regions 
instantly.

Regarding Japan, Korea and China, they have unique address systems each, 
so even normalization of inbound address data process did not work with 
one algorithm. Geocoder always works with data. Address data and system 
are made based on each local culture and history.

I won't discourage that we try to have an open geocoder at all.
Just want to avoid possible misunderstanding on this list that "i18n" 
geocoder can be a snap.
