 to-do
 -----
 
-   - Add a switch to use local cache for servers to avoid downloading each time.
    - Add command line switches to use specific server, override geo-ip lookup.
    - Add command line argument to run in server mode (no security) again rendering CSV/JSON file. I'm thinking websocket but not sure!
