Yep. My understanding is that v0.8 is by far the favoured approach. We  
can punt this out on legal-talk if you like but really, there's no-one  
at all arguing for the v0.9 version.

I think it'll be very common with paper maps and other renderings. If  
I go down to Blackwells and buy a cycle map (something I do with  
worrying frequency), I can't get the source data for it. Google don't  
give you the raw data behind their tiles at any price.

Most of the (waterway) maps I create are paper-only; they would add  
significant amounts of data to OSM if I were to use OSM as a base. (I  
don't right now because of CC-BY-SA.)

That's _probably_ going to be Collective AIUI, so not a problem. But,  
yes, the boundaries of Derivative are always, always going to be a  
headache and cause incompatibilities. That's why Science Commons like  
the PD approach and I can understand that... but we wouldn't get it  
agreed in OSM.

Very good idea.
