Is it possible for someone to have a look into creating an application that can perform certain actions based on the location.

This will be very similar to the Alarmed application only the actions will be triggered by the change in locations and not at specified times.

This becomes especially useful if we can turn off Wifi when we leave home or office and turn it back on once we arrive at the locations.

This can be done using the GPS or by the Cell Id of the current GSM cell tower.

I have used such an application on Andriod called Llama https://market.android.com/details?id=com.kebab.Llama

Thanks.
