Hi,

No, I'm afraid not - that's a Flash map - you wuold need a Flash developer - it's failry common (State selection) and could just pass a State search string to the UserGroup search results (not sure about users). Not quite the same, but have you seen the UserProfile/Google Maps integration on PokerDIY for poker players?

No, you need to download the free Google Module from bi4ce.

This module has been converted into a core DNN module and is in the Release Tracker at the moment.

Yes, it's a normally DNN module but it's quite complex to set up. They very helpful on the forums on Bi4ce and they have some great tutorials showing how to configure it and use it. When it comes out the core it will be a bit different, so if you can hold off for a few weeks you should consider doing this to make your upgrade path easier.
