David Kearns, writing in Network World, has offered an identity based view of what we do at iotum. Much of what we talked about as we were developing the early designs was the "Who, What, Where, When, Why" of communications. We boiled that down to the overarching concept of relevance, and ultimately identity becamse one of the 3 pillars of Voice 2.0. It’s nice to see someone latch onto those ideas.
He also mentioned that he saw us at ETel. One of the the exciting things I walked away from ETel with was the work being done in identity. Although not part of the main conference, for the most part, there were a gaggle of identity geeks at the show enthusiastically promoting XRI.
