this feature is already supported by the PDF 1.4 Specification. I think 
there was a FILE type object (or something like that) when I looked at it 
last time, so it should be doable with \pdfobject directly. I.e. you can 
"attach" a file to the PDF document (and that is probably how it is 
presented in Adobe GUI --- "attach" function)
