Have a look at Bluetooth low energy. I am working with some nice Modules
from Bluegiga (BLE112), they just announced a long-range version.
Although they are already very conservative with power and will run for
a while even with a button cell, a mercury switch (sorry) could trigger
them upon movement. You might be able to read a relative signal strength
(RSSI), but dont expect it to be good.
