Well, my main concerns were:

- I need to be able to figure out the ammount of disk space that a user is using, in a fast and easy way.
- There is a security problem with saving the attachments on a public_html directory.
- (this is the most important) I'd like to have all the database in one place.

So there is no way to send the content of a _big_ file to mysql without using a lot of ram?

Thanks!
