The best way to match a "thread" of messages is to use the "thread"
element. Your example (from bar@media's perspective) is then converted
to:
SEND (bar@media):
<message id='msg1' to='foo@media'>
<thread>123456789</thread>
<body>What's up?</body>
</message>
RECV (foo@media):
<message id='msg1' to='bar@media'>
<thread>123456789</thread>
<body>Nothin'. You?</body>
</message>
SEND (bar@media):
<message id='msg2' to='foo@media'>
<thread>123456789</thread>
<body>Watchin' the game</body>
</message>

Using a tag like this is technically outside of spec, which means that
other clients and components may (at best) ignore this <id/> element, or
(at worst) fail.
For more info on this spec, check out the current IETF RFC drafts:
