Ways to have WebPort users manage their UserDir

Hi folks! I was just wondering if anybody has come up with a solution that would allow WebPort users manage their personal folders. The Server File Browser in the client works well, but the WebPort-only users don't have anything similar. As a result, their folders become clogged with old uploaded files.

One solution I am considering is writing a protocol that lets each user manage the files in their own folder. Another solution would be to share their folder with each of them (a maintenance nightmare?). I thought I would ask you if you had other ideas.

Thanks!
