It can make things easier if the durability of the subscription is the
same
as the lifetime of the subscription. Message expiration is a separate
concept. Do we have a concept of message lifetime in WSN? Should we
discuss
that too?

Good point.  That would be in the queueing/replay spec that we never
fleshed out. :)  I think we should have a way of doing expiring it, even
if it is to rely on the underlying RM protocol to expire messages.
