Handsets, free wireless, and telcos
Russell posts about a future where handsets patch in to whatever networks are available - of different types. So that you might move from Vodafone, to a local community Wi-Fi network, and so on.
Things that I've noted about this:
1. Handsets already do this. When I roam to Spain, my phone switches between the various networks which are out there that have roaming agreements with Orange.
2. How will small-scale networks bill their customers?
3. How will these networks provide any accountability or quality of service?
