Hah. High-level attention doesn't drive deployment (except in a central-
planning or heavily regulated environment), a successful business case 
drives deployment.  

The opportunity for graceful transition was lost when we both failed 
to include transparent interoperability and then further provided no 
additional functionality to drive deployment.  Reference RFC 1669.
