What about a map based on the internet in its early days, such as this from Feb 1982:

ARPANET would reset to 1 neutral every turn, or something like that, and maybe people would start on routers (the rectangles) and get bonuses for holding everything branching off of a router?
Any comments/concerns? Does anyone think this'd be a fun map to play? Obviously I'd improve the graphics above and beyond a simple black and white drawing, but I'd keep the theme pretty retro.
