Wordpress Premium Member for Direct Downloads Link

Hi all.. I have warez site. It's not a huge site, but it's big site. It uses Wordpress. I post everyday, with filehosting links such fileserve, filesonic, etc. User could download from the link I gave. I want to create premium members in my site, so user could download from my site as direct download. So actually I have all files in my server (direct download) and some are in other servers (direct download too).. and the links I posted in the site are the filehosting links, not the actual direct download link from my server. some examples : the filehosting link : [login to view URL] the original direct link from my server : [login to view URL] What I want : - I want premium member system, embedded in wordpress users --> with payment gateway (paypal) --> I could create the package term, duration, & price - for each post, user could generate direct links for themselves. --> note that my site usually upload to 2 filehosting for each post --> the file is stored in my server, and it has unique filename. --> 1 post could have many files (like MP3 files and FLAC files) --> all original file locations are not located in the same folder in server, files are located in folder based on month's name, and some in random folder names. - limit the IP, files could only be downloaded by the premium member's IP generated. - the system could hide the original direct download links. --> for instance, the original direct download link = [login to view URL] --> user can't get the "[login to view URL]", it should be hidden, you could hide it by some method. - I could manage the expiration time of the generated links. --> I could setup the default expiration time of the generated links, ex : 2 days I have a similar php download class for this, but it's not what I 100% want. please PM me for more details about this project. only serious one please !
