Cheap Ad-hoc Network Nodes

As mentioned in today’s technology review, Ember (a Media Lab spinoff) is producing small low(ish) bit rate radios for use in self-healing/configuring ad-hoc networks.

It certainly looks extermely interesting but it also appears that the hardware won’t be available until July. For the applications I’m thinking of building this could be a suitable alternative to Bluetooth – it has proper ad-hoc routing and scalability unlike Bleutooth but quite a long range (up to 1000ft on low bandwidth setting which is far greater than I want).
