Yes, this looks good.

Now, another issue: what if the user is unable to publish new values prior to 
logging off, such as in the event of a network outage (or worse, some sort of 
attack) ?  It seems to me that the client should submit new values as soon as 
possible, perhaps right after logging in.  The client would then use both the 
old and new values for decoding messages received during that session.
