Would it be appropriate to continue this conversation on legal-talk?  
Talk is very busy at the moment and we have a lovely list of our own :)

With regard to these questions, lets make a clear distinction between  
the question (which anyone is qualified to raise) and the answer (for  
which one is likely to need to be a lawyer)! Possibly Ben is a lawyer,  
I am not sure, but in the past we have tended to form a legal opinion  
without ever asking a lawyer.

My company is taking legal advice on the licence and will publish the  
conclusions to the community. We will use the Open Issues page (http://wiki.openstreetmap.org/wiki/Open_Data_License/Open_Issues 
) as part of the input to our legal review. If you have questions then  
please ensure that they are mentioned on that page.
