The enterprise MVNO challenge.

"So the issue isn't that we're waiting for an enterprise MVNO to ride in on a white horse to save the day. The issue is who will address those enterprise requirements and how they will do so. I believe that there are companies today working on these very issues, and their business models are far more contained (and far more achievable) than the broad strokes of an enterprise MVNO. By working at the margins, these competitive providers will satisfy focused enterprise requirements and will help the carriers to offer a more complete set of services."
