Done, osm.org/browse/changeset/8498912

There is a corresponding note/section in the wiki osm.wiki/Bing#Precision

I've read through a few of the comments and what I remember is
a) have a look at major roads and prominent points to check the miss alignment of the BING images
b) missalignment can be different in every zoom level!
c) in potlache 2 the BING images can me moved by holding down space and move the background (use major points in the area to check)

so schwierig finde ich es nicht. Wie bei CC Lizenzen gibt es ja auch eine Zusammenfassung: http://www.opendatacommons.org/licenses/odbl/summary/
