It would be a better argument if the NTT guys hadn't said that they estimated 
6 months time before the code would be released, which puts us beyond 8.4. 
Now it is possible that the time frame could be sooner, but unless someone 
already has the patch, this reminds me a little too much of the arguments for 
including windows support in a single release because we already had a work 
port/patch set to go from.
