Scenario: testuser@ATHENA.MIT.EDU wants to zwrite to foo@LCS.MIT.EDU:

testuser% zwrite foo@LCS.MIT.EDU
Type your message now.  End with control-D or a dot on a line by itself.
Hi there, foo!
.
foo@LCS.MIT.EDU: Message sent
testuser%

At this point, foo@LCS sees:

Authentic Personal message  at xx:xx:xx on Thu May 18 1989:
From: A. Test User <testuser@ATHENA.MIT.EDU>
Hi there, foo!

To reply, foo@LCS types:
foo% zwrite testuser@ATHENA.MIT.EDU
Type your message now.  End with control-D or a dot on a line by itself.
Hi there, testuser!
.
testuser@ATHENA.MIT.EDU: Message sent
foo%

Scenario: testuser@ATHENA.MIT.EDU wants to zwrite to instance 'bar' in
LCS:

testuser% zwrite -i bar -realm LCS.MIT.EDU
Type your message now.  End with control-D or a dot on a line by itself.
Hi there, instance bar!
.
bar at realm LCS.MIT.EDU: Message sent
testuser%

foo@LCS.MIT.EDU sees:
Authentic bar message  at xx:xx:xx on Thu May 18 1989:
From: A. Test User <testuser@ATHENA.MIT.EDU>
Hi there, instance bar!

[If testuser@ATHENA.MIT.EDU had subscribed to instance bar, recipient
"*" in realm LCS.MIT.EDU, he would see the same message.]
