With NAT, it can work perfectly well. At long as each endpoint knows the 
other only by its publicly routable IP address, anyway.

There are probably web servers that run on RFC-1918 IP addresses. And 
plenty of home users who do. And yet, they can still talk to each other...

The /problem/ happens when you want to route between two entire 
/networks/ with the same network number.
