As you can now import Google's KML into Microsoft's Live Maps, a non-tivial questions comes up.
Erick Schonfeld from TechCrunch sums up that "Live Maps can now drink Google’s milkshake. Because all the customized maps that people have made and share on Google Maps can be grabbed as a KML file".

The example given is created by a user named Matthew B. titled PA & NJ Winter Camping that shows camping sites in those states - first on Google Maps, then sucked into Live Maps:

Being "Matthew B." - how would I like to be quoted, compensated or linked?

I certainly would want to be acknowledged in a decent way.

So: in which scenario would I like to be linked as broadly and deeply as possible? Let's assume a use case where valuable business relevant data has been aggregated. Putting it into KML is almost equal to give it away for free. And that's not a sustainable business model on a long run (except if you're out for eyeballs and advertising).

"Matthew B.": what would you do?

Joining the rush and adding to the the dealflow in late 2007, Microsoft bought Multimap, the second-most popular Web-based mapping service in the UK with it’s location-based search technology. Likely, Multimap will complement Microsofts’ existing services like Virtual Earth, Live Search, Windows Live services and MSN and allow Microsoft to compete with the predominant Google Maps.
