Yes, that's why we have a "renew-subscription" operation... :)

Hmm, that brings up an important point - I think the current specs
don't allow renewal after the subscription expires (because the
subscription object may be deleted from the server); I'm just going
from memory here, so I could be remembering this all wrong...

In any case, the client is free to renew or re-subscribe any time
they want, unless the subscription has expired and the server no
longer has any information about the subscription - a definite
possibility given the limited resources available in embedded
devices.
