377587 Rapidshare webui

i need a web user interface for rapidshare and megaupload User Panel - user will authenticate to login - the user panel need to have field where to enter rapidshare address to initiate the download - once user enter the address, the server then will authenticate to rapidshare using premium account username/password that we set at Admin panel, Then the user will be prompt to save the file - the server must only allow user to login if user connected from specific ip address, the reason is we only want to allow office users which connected through vpn to use this service - the server must not allow multiple connection using same username, If user is logged and another user try to login using same user/pass it must give error "user already logged on" - when user close browser or tab it must prompt to logoff, this is to avoid if user accidentially close browser and get error user is logged - the max user logged in time must be 15 minutes, inactivity in 15 minutes it should logout the user automaticly Admin Panel - The admin panel must have option to create username/password - The admin panel must have option to change the static IP incase in future we change the IP this is something similiar to torrent webui but the different in this is user will download the file instead server downloading it for them, The server only authenticate with rapidshare without letting the user know whats the password is for the premium account
