I have some large files (several GB each) that I would like to make available to customers to test my company's software. Due to the file sizes, upload/download times can be quite long, and I don't want to chew up my organization's storage space by uploading each file multiple times. So, I'd like to place the files in a single Dropbox folder and share the link with each relevant customer.
However, I want to make sure that anyone who I share the link with can't see who else I've sent it to. Recipients of the link may be early in the adoption process and can't be officially "exposed" as customers yet, and our customers may be competitors with each other, so I want to be sure that no one outside my organization can see anyone else who isn't part of either their or my organization.
For example:

In this folder, I am RK, BC is my colleague, and XH and ZW are employees at one of our customers. However, if XH and ZW weren't colleagues, I would want each of them to only see themselves, RK, and BC as members of the folder.
Does this feature exist, and if so, how can I enable it in shared folders? I would want this obscurity to propagate downwards to any sub-folders (and sub-sub-folders) as well.
