    One possible way to do this is to ping the broadcast address of the
    network that you are on. Then look at your arp cache with 'arp -a'
    (works on both Windows and *nix). As long as the number of hosts
    responding to the ping don't exceed the size of your ARP cache, the IP
    address you are looking for should be in the cache.
