He might be talking about jabber xmlstream. Yeah I do agree encapsulating
the file in an xml could introduce overhead (I remember doing this in my
former company where the file in encoded in base64). Why don't you just
transfer the file via http/ftp? Send an xml to the client containing the
address of the file and let the client application do the fetching.
