Secure Members Area

We currently have a small members area that uses a simple php login script.? It checks a mysql database and returns the appropriate access level.? It is controlled by cookies. We want a more secure members are that is integrated with our shopping cart and email server.? 1. We stream flash videos and the swf file names can be found if someone? checks the source code.? So, we would like the php/html to not be displayed when someone tries to look at the source code. 2. We would like a customer to only be able to be logged in once, i.e. to not be able to share their login details.? Maybe logged in once isn't the correct way to describe it. 3. Customers sometimes experience difficulties logging in due to the cookies so another variable other than cookies would be quite acceptable or perhaps a better way to use cookies 4. We want our shopping cart integrated with our members area.? We have a pdg e-commerce cart.? A? member should be able to? check their expiration? date after they login and renew online.? Their access level should be adjusted in the mysql database according the to the product they purchased.? We don't want recurring billing though.? We don't like to store Credit card information on our server 5. We have special email software on our server.? We want the members area to send out renewal notices and email a report (a web page)? three times each week to specific members ## Deliverables I don't know that a desk top application is appropriate.? It seems like it would need to be a series of php web pages with the appropiate forms and scripts or maybe some plug for dreamweaver where the appropriate scripts could be added to new pages.? It? needs to be flexible enough that the member's area web pages can be editied easily in dreamweaver.? If we want to change the page layout, colors, add logos or free products, change font type - etc.? We want to keep our current web site look and feel, but also have design flexibilty in the future. We are looking for function web pages that communcate with our mysql database, shopping cart, and email server.
