Business edition - so great!! Question on access

Just purchased the business edition and it is just so great. Had a look at the autogenerated products from images/files and it will save me SO much time in product creation as I am a photographer and will come home with 100 to 200 products that need to go up on my site. And you create a template product to base all the autocreated ones on. I imagined I would have to go in and make adjustments to each product.

Have to see tho how the access control is going to work for me. Suspect I will need to create the users. Was hoping for functionality that would let me password protect an area under a single password but that will create an issue with purchasing. The buyer account has be be separate from the the user account that has access to the restricted area.

Process should be something like:
Log in with a common password distributed to the users> view images > select images for purchase > go to cart > create account with purchaser info > complete purchase > send email for image download

Any thoughts on how to achieve this?
