How about sending and receiving it as an XML file? I don't think you can append from an XML file (I've never worked with them) but I would imagine you could

XMLTOCURSOR(received file,tempfile)
USE sending2
APPEND FROM tempfile

As I said, I've never done this so you'll have to work out the correct parameters in CURSORTOXML() and XMLTOCURSOR() to get everything synched.
