    // This is an illustration of how one could use virtualization techniques to
    // allow running applications on virtual machines talking over simulated
    // networks.
    //
    // The actual steps required to configure the virtual machines can be rather
    // involved, so we don't go into that here.  Please have a look at one of
    // our HOWTOs on the nsnam wiki for more details about how to get the 
    // system confgured.  For an example, have a look at "HOWTO Use Linux 
    // Containers to set up virtual networks" which uses this code as an 
    // example.
    //
    // The configuration you are after is explained in great detail in the 
    // HOWTO, but looks like the following:
    //
