At the last WG meeting, we talked about how to add lifetime information to 
addresses for services (for example, DNS server addresses).

So, what are the requirements?  Basically, we want to be able to inform the 
client the time over which it can expect the service address to be 
useful.  The client can then re-contact the server to confirm the continued 
validity of those addresses or find out about new service addresses.

Question - is it useful to have a separate lifetime for each service or can 
we make a simplification about lifetime information that applies to all of 
the services configured on the client?

Are there other requirements?

- Ralph
