    I think you have at lesat the two following solutions:
    - Two machines: the first one sends the real GET to the second one, which
    forwards the request to the target after sooping the IP (with Hping2 for
    instance).
    - Just a machine, a Windows one: a programm such as RafaleX should allow
    you to send whatever you want, even spoofing the MAC source address. Nemesis
    can create a custom packet (but i am not sure the payload can be an HTTP
    GET)

    Hope these hints will help!
