    Say you have a wireless router, and you don't really want to restrict too much, but your neighbor keeps using your bandwidth. Sure you could tighten up the security and kick him/her out, but another option is to setup in your configurations a valid set of ips and mess with the others. One trick is to reverse all the text in the html, but another one could be the injection of some java script. Here's one: javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.images; DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=Math.sin(R*x1+i*x2+x3)*x4+x5; DIS.top=Math.cos(R*y1+i*y2+y3)*y4+y5}R++}setInterval('A()',5); void(0); Please forgive the horrible formatting. Stuff this in your browser at a site with a lot of images... think ghosts flying. Client side effect only.

      Nice. I think I saw this little trick on Digg not too long ago. Cool effect!

        Sure. Copy the javascript, and paste it directly into the url field without the url. Just the javascript. And hit enter.

                  Interesting. In my FF (2.0.0.1) it just shows "200" in the upper left corner on the otherwise blank screen.

                        Well, you have the option of intercepting all html since you're at the access point. So, theoretically you could reinterpret any html coming down the pipe. With that you can plug in anything you want. Hence in this case, you can make all the images fly around like ghosts on their page. After a while, the offending bandwidth hijacker would hopefully get frustrated and stop stealing bandwidth.
