This *does* break horribly for digital signatures - I suspect that both
an S/MIME and a PGP signature would be invalidated by changing the embedded
file into a reference.
Also, things get interesting if you try to forward the mail along with the
attachment - I do *not* think it would DTRT with the reference (in other
words, the recipient would just get a dangling reference, not the file.
The forwarding problem is probably solvable, I suspect that the digital
signature one is *not*, unless you find a way to reconstitute the original
on a byte-per-byte basis (and making sure that for the corner case of
a PGP or S/MIME signature that actually covers a *reference*, that we
do *not* expand the reference as that will also break the signature....)
