I don't fully understand the extent of the 'share alike' clause in the CC-BY-SA license. It states:
"If you alter, transform, or build upon this work, you may distribute the resulting work only under the same or similar license to this one." (from the deed of the 2.0 version of cc-by-sa, http://creativecommons.org/licenses/by-sa/2.0/)
Consider this case: someone wants to use OpenStreetMap data augmented with POIs from a closed source in a routing application. This routing application is then used within the company for which it is built, for commercial purposes. Do the POIs need to be released under CC-BY-SA? The word 'may' implies they do not.
I'm interested in your opinion.
