Hey Maning,

I'm going to take a stab at answering this, since I'm trying to
understand the implications myself.  If I'm wrong hopefully someone
will let me know.

I think since you are releasing the combined data as a product i.e.
WMS this is okay.  If you were offering download of the data then you
would need to make everything available.

I think you would do this in all of these cases.  I am not sure the
most appropriate case for WMS though,  Perhaps in the metadata
returned from the GetCapabilities request?

This should be fine, these are considered "products".  You just need
to continue to attribute OSM appropriately.

Hope this is helpful and someone corrects me if it doesn't make sense:).
