First, the assumption that plotting points on a map is a derivative work 
is one I question. If the points are sourced from GPS or something, then 
you already know the lat/lon of the points. You're not making a 
derivative in just overlaying some dots. In fact, one legal off the 
record opinion I got said that deriving a point wasn't a derivative work 
either as you were deriving a fact. IMHO IANAL IANAC.

Nick can this be a Q to the lawyer(s)?

Second you don't have to release the data you have to let me copy the 
entire map CC-BY-SA. You don't have to give me the illustrator file you 
made or whatever.

have fun,
