You send entity capabilities ("caps") when your capabilities change. So
if your client has different capabilities (i.e., supports different
features) when the service is running, then it is appropriate to send
new caps data when the service is running (and send new caps data when
the service is not running). Alternatively you could create your own
custom namespace for service data (or use XEP-0004 or whatever) and
advertise that data via presence (may or may not be appropriate) or via
a pubsub node (probably using "personal eventing", see XEP-0163).
