That's pretty much option 1, albeit implemented slightly more robustly
than I was thinking of. But my data's not sensitive, so there's no
advantage in losing it on sending it to someone else, and in fact I'd
much prefer it was retained if possible.

A nice feature of this approach is that you only have to modify the
file once, not every time your data changes.
A drawback is that if the file is sent to somebody else, the
information doesn't go with it. (Which, depending on what the info
is, could be considered a benefit: people have gotten in trouble for
forgetting about the metadata Word attaches to their documents.)
