AFAIK, server side copying of attachments is not possible.

The same as above, I don't think this is possible right now. It would 
require a lot of server side processing of the database if one 
attachment is equal to any of all other documents and would slow down 
attachment uploading significantly.

Maybe you could store the attachment in a separate document from the 
original one and store a link to it?
