Prototype currently in progress using the MSP430G2553 launchpad and the Booster XL battery pack for launchpad (http://au.element14.com/element14/boostxl-battpack/li-po-battery-boosterpack-for-launchpad/dp/2313552). This will require some additional vero-board work to house circuitry not included on the dev boards. Software development is progressing well, the design is based on re-usable modules which can easily be configured without code changes. Software will go onto public GitHub repo as soon as a reasonable version is available. Exciting!
