Hmm... what year would we be going for exactly? I'd definitely be interested in running a Mojave nation as an independent New Vegas. The courier being the leader. However if the NCR is fracturing I think it may be likely that it's between the Kimball and the forces opposed to his rampant expansion. 

Oh and regarding Google Maps... if you can figure out how to remove the markers, that would be incredible as I've neverfigured out how to do that.
