I remember the NSA refusing to send a core file for us to debug a FrameMaker crash they ran into, since they knew that their document could be extracted from it. Perhaps this is the sense in which the .doc files are being sent; in the trivial case, they may simply be mapped into memory, which is then part of the dump that gets sent.
