This presentation is entitled "Cross-Operator Federation of Customizable Network APIs" and introduces the OneAPI Exchange which is an infrastructure doing exactly this.
The intention of this talk is to present an API strategy that should allow mobile network operators (aka carriers) to expose their unique assets across operator boundaries.
The benefit for a developer is that s/he only needs to set up one relationship with one operator but can increase reach to all customers of the other operators.
This could be a strategy for operators to increase relevance in the API and mobile app world and to gain back developer mindshare.
I gave this presentation at the SDP Global Summit (http://sdpsummit.com/) on September 19, 2013 in Rome. The targeted audience is carriers and vendor or IT solution providers to carriers. SDP stands for service delivery platform and basically is a more or less sophisticated API management gateway. (Some might argue it is much more than that but this is what I focus on.)
