I agree that a fix is urgently needed for this, and don't see any 
problems from pushing the fix as is, so long as it is only as a stopgap 
measure.  I think we should push hard on getting a more permanent 
solution in place ASAP, so I'll take this as an action item to make sure 
the appropriate requirements get communicated to to the OpenFlow consortium.
