Is it possible with Adobe Acrobat to create a PDF that has multiple usernames/passwors for read access and individualised watermarks or with any other adobe product?

Hi,

  We're looking for a solution where a PDF can be created and distributed to multiple people - each with their own username/password to open - and also when opened created a user based water mark on the document. Is this something that can be done inside Acrobat Pro or is there a higher end product that does this?

Thanks!
