Erk. I'd guess (IANAL &c.) that the licensors are the individual OSM  
contributors (through the derived work provisions) and OSMF (as the  
creator of planet.osm).

Fortunately, both the contributors and OSMF specify  
www.openstreetmap.org as the URI to be associated with it!

The attribution-of-original-authors part of CC-BY-* is the bit I feel  
least confident about. I'd agree with your suggestion _if_ the licence  
doesn't insist that every contributor has to be credited. But it's a  
bit of a stretch to reinterpret "conveying the name" as "conveying the  
URL of a webpage where the name is listed" - especially for paper maps.

Look at wikitravel.org for an example of the problem. They're CC-BY-SA  
licensed, and to comply with the attribution requirement, every page  
footer has a list of contributors to that particular page. (In the  
very longest lists, this is abbreviated slightly, by means of an  
'...and [[others]]' link.) We don't do that.
