What about when a user switches (within five minutes) between two different
clients (resources).

If the message sender does not specify a resource then the message could be
replayed to the second client.

Perhaps the message IDs should be stored on the server, not locally on the
client.

The client would have to allow messages stamped up to five minutes before
the logout time.

Also the timestamp cannot be stored locally. Since there be more than one
client.
