Steno principals are alive and well. Covert channel transmissions are alive
and well. Both were used to bypass compartmentalization on a certain secure
OS. If anyone needs to encode data in valid HTML to tunnel it through a
firewall, it *will* be done. Several years ago, we had implementations of
telnet over email, I am sure modifying it to do telnet over HTML would be a
rather trivial task.
