I would love to be able to plug in two locations and visualize on a map the path my packets would take travelling from here to there. A sort of visual traceroute. One problem I've had with existing tools is that it's hard to find a server in a given place, even if you know that place has internet. For instance I was facetiming with my partner who is abroad in africa right now, but I'm not sure of a server to [traceroute] against in the country she's in.
