The one weakness of using pdfpages, as touched on by an earlier thread, is 
that widget annotations will not be preserved from the original document; 
at least not with the standard version of pdfpages. In this regard, the 
pdftk route nominally works. However, I have some documents where it gets 
confused by the amount of embedded JavaScript with the result that the 
background is not added. Therefore, as with all software, I'm afraid
it's a case of user beware!
