New Sydney road signs use low-power 'E-Ink' technology and can be remotely updated:
The NSW Government has tapped the same technology you use to read books on your Kindle to create low-energy street signs that can be remotely altered.
The electronic paper road signs, which have been installed across Sydney, are the result of a partnership between Roads and Maritime Services (RMS) and Slovenian technology firm Visionect.
[...] An RMS spokesperson told The Register that 15 of the new signs 'were successfully trialled in the management of traffic on George Street in the Sydney CBD and a second rollout has since been completed in the Moore Park area.'

the signs are solar powered but that power can easily be drained if the radio is constantly receiving bad information. so DoS attacks aside, how secure do you think these signs are?
