A quick update that make the application works with Intel wireless cards 2200 and 3945abg, still need testing, you can download it there (XP) and here ( Vista)
Thanks for feedback ! this is still a beta and we need as much bugs reports as possible !

Remember, this application use ARP spoofing technic which is, “ok” to use in a home local network, but don’t try to spoof your internet cable or company networks.

Use it at your own risk.
