Warmspots

Not hot, warm. Meaning, a portable router contained in a small wireless device that an individual carries around with them (could even be a cell phone). Create a mesh of users. Assume that some percentage of people are always near an actual hotspot and therefore wirelessly connected to a broadband connection. Make this mesh generally available and you now present voice carriers with a big problem in the form of VoIP. This is already happening on the vehicular level. Given the potential for disruption, I'm not surprised by reports like this or this. Seems like a great way to wipe out the strangle-hold wireless carriers want to keep on access to their infrastructure. It could also mean that, like the restriction-free WWW, real innovation in the wireless space may finally bloom.
