Get MAC address of remote PC?

I need to get the MAC address from a PC. The code I've written so far is here (this is only a small part of the code).

public byte[] getMac(L2PcInstance player)
{
    try
    {
        NetworkInterface ni = NetworkInterface.getByInetAddress(player.getClient().getConnectionAddress());
        if (ni != null)
        {
            byte[] mac = ni.getHardwareAddress();
            if (mac != null)
            {
                return mac;
            }
        }
    }
    catch (SocketException e)
    {
        _log.log(Level.SEVERE, "No MAC address.", e);
    }
    return null;
}

This code finds the MAC of the PC I run it on, but I need to get the remote MAC.

You can't do that in Java, and if you do some research you will find that the MAC address isn't really much use to anything except the Ethernet layer and the NICs attached to it.
