The PSFK news blog has an interesting item about major universities that are using dogs equipped with a variety of technology tools to better conduct rescue efforts in the event of a disaster.

Since WiFi is two-way technology, it can be used to allow a controller to communicate with the dog, as well as getting environmental and even visual data from the dog's location.
