Yes, I have now switched over the OSM database on toolserver to be 
imported from the ODbL licensed OSM data. So all data derived from the 
toolserver's osm database now also needs to be licensed ODbL. The tiles 
rendered on toolserver (http://{a,b,c}.www.toolserver.org/tiles/ ) and 
used in a number of wikipedias through the osm-gadget, as well as the 
tiles/data in WikiMiniAtlas are therefore now also being derived from 
ODbL data and need to be attributed accordingly.

I presume the tiles themselves, following the example of osm.org, remain 
under CC-BY-SA. But by whom and where is this actually officially declared?

My understanding is that the mobile team currently don't use the tiles 
generated on toolserver though and instead use the open.mapquest.com 
tiles for the moment (which according to Mapquest's attribution haven't 
switched to ODbL yet)? The idea is to develop and test a puppetized 
installation of the rendering stack on labs and then run it on a 
separate production server.

Licensing questions should probably be handled consistently though 
between toolserver, labs and production servers.
