Hi there,

( that will probably bring some more fear to the different API/server 
admins ;-) )

In france, next to the cadastre's agreement of using their data for OSM, we 
might soon be able to import something like 60% of France's builings.

The remaining question is : should we do it ?

- quality concerns/tests are on their way
- semi-automated imports are being developped to spread the load in time (and 
get a quality idea of the data we have)

My RFC on this dev list is, what negativ inpact could that bring to OSM db 
servers ? on rendering servers too ?

Values expectation are roughly :
- 10,000,000 builings (from a single house to church to towers to many others)
- composed roughly from 4 to ~50 nodes

Thoughts are welcome
