When I woke up this morning I thought of an alternate way to do this:

1. Requesting entity sends presence to responding entity and includes 
entity capabilities data, including a namespace of 
'http://jabber.org/protocol/disco#items+notify' (indicating that it 
wishes to receive notifications related to disco#items).

2. Requesting entity sends standard disco#items request (without 
inclusing pubsub <subscribe/> since the caps data resulted in an 
implicit, short-lived subscription).

3. Responding entity sends standard disco#items response.

4. Responding entity sends subsequent notifications.

5. When requesting entity goes offline, responding entity receives 
presence unavailable and terminates short-lived subscription.
