paper-net n.
Hackish way of referring to the postal service, analogizing it
to a very slow, low-reliability network. Usenet sig blocks sometimes include a
"Paper-Net:" header just before the sender's postal address;
common variants of this are "Papernet" and "P-Net". Note that the
standard netiquette guidelines
discourage this practice as a waste of bandwidth, since netters
are quite unlikely to casually use postal addresses. Compare
voice-net, snail-mail, P-mail.
