 This is a problem but the licence authors are working on it.
 
 At least the most common ones like GPLv2 or later, LGPL, GFDL and

 This will make things worse rather than better as it will fork some
 OSM derivatives into four different incompatible streams.
 

I don't think this will make forks more likely. Thinking of the use
cases I mentioned I think people will improve OSM to suit their needs,
then create the flyer/movie/whatever as a derived work from both the OSM
data and something else. The flyer wouldn't make sense to somehow merge
back into OSM anyway.

 Use case 1:
 Creating a flyer about some topic where images from wikimedia commons
 are combined with a map created from OSM data. According to
 http://commons.wikimedia.org/wiki/Category:GNU_licenses there are
 1319405 GFDLed, 6127 LGPLed, 13575 GPLed and over 40 CC-BY-SA
 (different versions) images on Wikimedia commons.

CC and the FSF are discussing FDL/BY-SA compatibility and Wikipedia is
committed to moving to BY-SA.

BY-SA 1.0 is gone, we have to let it go. ;-) Versions after 2.0 are
compatible with each other and with OSM.

 Use case 2:
 Using OSM in a documentary movie: Places relevant to the movie's topic
 are shown on a map created from OSM data. Zoom in to a place, then
 there's a movie sequence about that place, repeat for other places. For
 the documentary footage placed under a CC license from archive.org's
 moving image archive is used.

This use case seems like it should be possible with the current
licence unless I've missed something again?
