We don't do the static lease thing - we have a really fast back-end  
database, so it's no skin off our nose to allocate "fixed addresses"  
dynamically.   The way we do reservations is to mark an IP address  
from a pool as "reserved," and then we have logic that looks at the  
incoming request from the client and decides whether to try to  
associate with that lease or not.   If the lease isn't available, no  
association occurs, which means that we don't violate the protocol.    
So if the association logic can match more than one client, there's a  
potential for the second client that matches not to get the fixed
