I would like it if people could access files that I put on acrobat.com without having to send them a link in an email. This is assuming that a file structure will be created in the future. People could then see all the files that I have created for them and download the ones they need. This could be done by creating a folder and granting access to certain email addresses. You could even take it a step further and create a login and password for each folder that you wanted to grant access to.

Example: I am a designer and I create 2 logos for 5 companies. I would create 5 "accessible folders", one for each company. Customer 1 would log on to the personal web address that I provide them such as "acrobat.com/angryape/customer1" . A login screen would pop up and after they login, they can see the 2 files that I uploaded for them to view. They can look at them on screen or download them. I would create folders, passwords and a web address for each customer.
