Scott talks about the DevNet and the BOPNet - the existing developed Internet and the emerging social networking services on the mobile platform meant for the BoP. Ultimately, the whole Internet is nothing more than a huge social network on the global scale, allowing us to connect with, share with, communite with and, perhaps, do business with, anyone else out there in the world.

And while the DevNet is accessible by anyone with a browser and a data connection, regardless of device, the same is not yet true for the bopnet. Its still under construction, with bits and bobs and pilot programs, spread around the developing pockets of the world. It works on mobile phones and its simplest components use only voice and/or sms as a means of communications. Basic social networks provide the semblance of the "read write" aspect as chat forums, games and news proliferate. Underlying the chatter is the increasing advance of the financial transactions layer.

Creator of the blog Mobile Banking, CEO of Fundamo, Hannes van Rensburg, has been posting of late on the eventual need for all these mobile payment systems to start becoming interoperable (a word under debate on his blog). This is inevitable if a true transaction layer is to emerge underlying the mobile net particularly for the BoP.

Lets take these thoughts a step further, and contemplate the Border Zone between the BOPNet and the DevNet, the bridge that we're slowly building across the global digital divide.

Will it continue to be the no-mans land that currently exists between the formal economy and the informal, unorganized sector? Or will it be able to provide a way for the cash based economy of scarcity from the base of the social and economic pyramid, the teeming billions of unbanked, to interact with and permit the two way flow of resources, connecting with the far wealthier formal economy?

At this point, it would be interesting to begin observing those spaces where these two economies already begin to merge or connect. In the real world, how and where does is exchange take place, which touchpoints provide value for both sides and how does value get created, infusing new wealth into the hyperlocal BoP economies, inside urban slums and between the rural and urban markets?

How does this translate into lessons for the future development of the technological roadmap? What opportunity spaces for innovation emerge?
