I hope this is allowed if it is not then I apologise and please could an admin or mod remove it thanks. Ok so I have just come across this tool. The way it works is you put the tool on your computer and you close your lid and your walk about and listen for certain sounds and when you have the right sound you have access to someones wi-fi. I won't go into to much detail as it explains it on the site. Code: http://quicklz.com/outssider/ Anyway it could be handy it might not be I will let you decide. Thanks Godmonkee P.s it's not my tool and I am not affiliated with it in anyway like I said I just found it, I wish it was my idea as I like it and could have made some money of this.
