Hi,



The "board" of Champs Libres (my society founded one month ago) had a 
meeting this afternoon and we decided that it was very important to give 
help to osm-be. So, we agree with setting up a server for tiles or WMS 
if you think this may be useful.

As a I understand, the use case is "to be able to mix WMS layer from 
AGIV / Région Wallonne with openstreetmap". This is not possible until :

1. AGIV / RW serve WMS layers with projection EPSG:3857 or 900913 ;
2. We have tiles in those projections ;

So, we may reproject WMSs into 900913/3857 (1) or serve tiles (2).

For 1, this will force us to "capture" every WMS and serve it again. I 
am afraid that we might have a delay before inserting WMS. I wonder also 
about the legality of such use (I may ask RW for authorization).

For 2, we know how OSM goes, and an advantage I see is that we might 
have other styles later, if we need it.

What are other advantages of every answer to those question ?

Julien

NB: our server's provider have some problems those days... We will have 
to wait their new products to be available. This should be done within 
end of this year.

@André & others :

Arlon was great. I spoke about OSM as a community project, how we works, 
what we do, what are the value of the community, ...
