Hi all,

If people have a modern Telefax machine, have you ever
tried out to send a GnuPG signed Fax?

I was thinking about the following:

One prepares his message in the following way:

---begin message---


--end message---

Then saves the message, detach signs it and converts the
detached signature as QR-code which is put then also on
the Fax document, while the receiver then OCR scans the
document and decodes the QR-code.

The --begin etc. markers should be used to detect where
the OCR scanned document begins and ends to have later
a good signature.

Well, just a thought.
