URGENT - For Facebook Experts

Hey, This is a quick $150 project for expert. If you are facebook expert you might be knowing that there are many ways to get UID (user ID's) of facebook members. In this project what i want is: Whenever user visit to my web page (a simple HTML sales page) and if user is logged in to his facebook account, Script should automatically save his UID in the MYSQL database and provide me with the download of: NAME: UID: of every person who visited my page HOWEVER (THIS IS IMPORTANT) i don't want the user to provide any permission/app permission etc. Everything should run in silent, in background. For example, suppose 'John' is logged in his facebook and he visited my site then, JOHN and UID of john, should be saved in MySQL database Like John - 12300124540 and i should be able to 'import' it as .TXT from some page. REMINDER: We are not getting any permission/ app install etc from user. DO NOT BID: 1) Many developers say this script is not feasible (impossible to create) however i have seen many sites like : [login to view URL] that generate user ID from the user's facebook profile URL. So, if you could some how find the users facebook profile URL like: [login to view URL] then i think this project could be possible. DO NOT BID if you are unsure. 2) 10% Escrow: I will start with 10% escrow with selected bidder. 3) No script No Money: I am not paying for free or your efforts. I am paying for the 'final working product'. 4) Once again, no app installs/permission etc: I dont want to get user to click on 'okey' or give some permission. Only an expert, could do it tactfully.
