Performance on this is pretty impressive. Most of the code for this has generally been terribly slow and inefficient (eg BeEF).

Very cool. I ran this on my laptop connected to my school's WiFi network and found 65 alive hosts.

You need to be very careful about what you do on other people's computers. Make sure you get permission and are able to explain what you're doing.

Very cool! But your subnet "detection" seems based on a broken assumption.
