In Adium, we handle this for the MSN Display Name, which has a similar  
behavior (stored online, may be updated elsewhere, should be shared)  
by setting a separate boolean preference when the changed is made  
while the account isn't connected.  When the account connects, if and  
only if that preference has been set to true, the local value  
overrides the server value, and the preference is reset to false.

Perhaps a similar behavior would be the compromise for best behavior  
with the XMPP icon?
