I need a module that will display an Admin-defined selection of files for a customer to download, i.e., each customer should be able to download only the files, from a collection of files, that Admin has enable for that customer. Also, Admin needs to be able to view a variety of lists, i.e., a list of customers who have access to each file, a list of all files that are accessible by a certain customer, a method for including or excluding files to and from a list.
