I have been requested to ascertain if its likely to produce a Facebook application that "hugs" people on the special microsite.

Particulars: We are creating a microsite. Customers can sign in there using their Facebook Accounts. Then it ought to be easy to "hug" others (like poke, however it needs to be hug :)). Then there must be a ranking, which Facebook user hugged probably the most customers. Is possible?

Thank!
