Hmm I like the idea but I'm not necessarily sure if this would be directly useful for filedump. Filedump is not meant to be a social thing, is it? I thought it was just to be used for managing files.

I think it would be better as an addon or part of the addon enabling member-based filedumps.

Think using it for a team collaboration tool. For example, some companies may want to upload design files and let people leave notes.
