I remember way back in SQL Server 2008 they introduced geospacial data and queries that may make this sort of stuff easy. There were a few demos floating around on how to interact with this sort of data, which I'm sure you could google up without much effort. Unfortunately I haven't had the joy of playing with it myself, so that's as far as I can take you.
Of course, it would introduce a dependence on SQL Server to provide all the grunt, which may not be acceptable for your solution. Carl.

I see the problem broken into a few pieces: * defining the complex regions and hoping that there are public sets of coordinates that define famous boundaries like countries and states * zooming around the map to select small regions (like Luxembourg) * hit testing and pleasing animations on mouse over and click. If anyone has been through this exercise before then I'm keen to hear advice. I'm hoping that I won't have to do everything manually from first principles with raw code and drawing primitives.
