One potential advantage is getting feedback from the ESC on things like RPM and battery voltage. At the moment I suspect most of us are building external sensors into our projects and really this is redundant as our ESCs already know this, they're just not telling us!
Also like Chris mentions, the flexibility of having different interfaces (potentially at higher frequencies). If you ask me PPM is a bit of a bizarre way to communicate. I believe open source servos similarly provide other methods of communication (http://openservo.com/)
For quadcopters, which need really high performance ESCs (100 hz or better), the commercial alternatives are expensive and often inflexible. But I don't see the need for this for standard fixed wing aircraft.
I like the idea of open source. Anyone who have an opinion of the main pre of this one? Power, customizability, price, quality, early making of technology available, others?
