• From the ROWETEL site:

    “Codec2 is an open source low bit rate speech codec designed for communications quality speech at around 2400 bit/s. Applications include low bandwidth HF/VHF digital radio. It fills a gap in open source, free-as-in-speech voice codecs beneath 5000 bit/s. It is released under the GNU Lesser General Public License (LGPL).”

    This is pretty awesome stuff. At 2500bps you could easily stream voice over ZigBee/XBee mesh networks. You could probably even use those $5 RF links for P2P communication.

    As if that weren’t enough this site is a bunch of cool projects. One of particular note is the Mesh Potato. It is aiming to be a: “The Mesh Potato is a 802.11bg mesh router with a single FXS port. It is designed to provide telephony via VOIP while simultaneously facilitating a mesh cloud. It is an open hardware and open software design. It will run off a nominal 12VDC, from either a mains supply or solar PV system, and be priced in the range of currently available Wifi routers (sub US$100).”

    My guess is that the software could probably run on many current network enabled devices (Android, PSP, N900, etc.)
