It would be very beneficial to share by file instead of just folders.  Is this under consideration, in the roadmap, or is there a reason this isn't allowed?

Folder sharing is nice, but definitely limits functionality.

For example, I would love to use FB & RSS sharing features, but I don't necessarily want to share every picture I have in a folder.  For example, if I put 100 photos in my local (c:) 'Vacation Photos' folder, I may only want to share 15 of them with friends on FB or via RSS.  It's not practical to split my vacation photos into multiple folders locally and then share the new folder w/15 photos.  

Keep up the good work, and I'll keep spreading the word on Pogoplug (hopefully I'll be able to endorse the FB & RSS features w/individual file sharing too someday :)
