They won't license their software any time soon. They decided against it in the earliest days and it really wouldn't fit with the Uber brand today. Maybe once they are a public, growth from new markets has slowed and they are chasing profits they sign license deals to open up otherwise closed off markets. I am skeptical that many taxi commissions in major cities would line up to license though. As of now the current system obviously works well enough for them (and that's to say nothing about the little those orgs likely trust Uber). If they have successfully banished Uber (etc) to the point where Uber wants to license software just to join the market I'd expect revenue split terms would be so unfavorable to Uber that they would not be interested.
