Thanks, Richard, for the answer. And yes, it's help. I conclude that 
what I want is possible but I have to do my own "OSM server".

But, why don't you integrate the layers in OSM web page? Now we could 
choose Mapnik, Osmarender, ... why not put another possibility: "choose 
layer". Yeah!, I know it's a littble bit work (!) to do but it could be 
cool!. Very cool and (I think) useful....

Perhaps in talk-devel? ;-)

Thanks another time, Richard,
Xan.
