Consider, if you will, the plight of the horse-drawn carriage. Hardly more than a scant hundred years ago, it was the conveyance of choice for anyone heading anywhere that was not easily accessible by rail. Along comes the automobile, and the carriage began a descent that ended with its extinction from the realm of the practical. Now, with the exception of some Amish communities, the occasional ride through Central Park, or a once-in-a-while Anheuser-Busch promotional appearance, the horse-drawn carriage is a matter of memory. A ghost of nostalgia.

The change wasn't sudden. There were hundreds and thousands of people still traveling by and receiving mail from horse-drawn carriages for decades after the arrival of its horseless cousin. In fact, worldwide, some areas still see something similar from time to time. Such is evolution. Such is transformation.

In the world of communications, we have our horseless carriage:  All-IP networks are clearly the wave of the future. However, they're not overnight projects, and it will take time, effort, and money to complete this new paradigm. To transform.
