"What do you do when you find someone else stealing bandwidth from your wireless network? I don't care, but this person does. So he runs 'runs squid with a trivial redirector that downloads images, uses mogrify to turn them upside down and serves them out of it's local webserver.' The images are hysterical. He also tries modifying all the images so they are blurry."
What we really need is a simple tool in our tasktray that tells us when a new computer comes onto our network, gives us a look to see who it is and lets us blackban them or not.. simple... I feel like getting someone on rentacoder to do it right now.
