EMF Camp in the UK is looking at this and doing an experiment: The same badge back with most of the electronics on it, the same battery, and a swappable front plate to give some variation and new functionality. The badge is intended to last 3 events (6 years) and has thus far done 2 events.
We're also hoping the expansion connector might be used by other boards - i2c, 4 fast gpios, 5 slow gpios/pwms, 700ma of 3.3 power. A standard similar to SAO for identification via i2c flash
