Sorry, I thought you had asked about tracing from tiles.

Tiles can be put under CC-BY-SA with no problem; in fact the main OSM 
tileserver is likely to do that.

A database created by tracing from these tiles might however be subject 
to the limitations I have outlined in my previous email. Whether or not 
CC-BY-SA makes such a distinction or not is not relevant. I tried to 
explain this by referring to the related case of patents (here, too, 
CC-BY-SA makes no distinction), but I understand it is a difficult 
concept to grasp.

Bye
