Attachments Anywhere

[Carco]

I believe attachments should be an independent entity..

I would like to see some other feature like: Giving different permissions for each attachment..

For example:
I have post number 1, and its attachment should be downloaded by any visitor..
I have post number 2, and its attachment should be downloaded by members only..

AND BOTH OF THE POSTS ARE IN THE SAME THREAD

I'm not sure if this is doable without making them independent.. OR making them independent will make the permission process much simpler, and more elegant.
