So if you didnt get the email, Silverstripe launched a [url=http://www.silverstripe.com/partners]partner program[/url] recently. Im guessing the team intergrated that map into their Silverstripe installation.
Is it possible for any of the team to go through how they intergrated that, or at least what they used to do it. I have a client that needs something very similar to that.
It does not use the maps module. All it is is a custom google map (made on maps.google.com - including the markers) and embedded using an iframe. When we get more partners we update the map manually. Sorry guys no magic :)
