"Stateless" in this sense is more about graceful recovery from service  
interruption / hot-plugging than necessarily that "no state" exists on  
either end.  The NFS protocol is a good example--it allows file  
servers to be restarted and so on without really any impact on the  
client, e.g. no remount is necessary, it recovers instantly.

A stateless way to implement subscription models is a lease.   
Subscriptions are renewed every X seconds by the client, otherwise  
dropped.
