A nitpick. I am puzzled by the word "decay" in this context. Electron 
transition between energy states in atomic clocks is not decay.

Nuclear decay is hardly related to clocks as well. Observation of photon 
frequency change due to propagation in gravitational field of the Earth 
was a really impressive experiment. However radioactive decay was just a 
means to get excited nuclei. Emission and absorption of gamma rays is 
still a transition between energy states, not a decay. Anyway I am 
unaware of *clocks* based on Mössbauer effect. Despite extreme precision 
in respect to frequency change, difficulties with implementation make it 
impractical.

As to a GPS receiver, it should be doable and 169.254.x.y addresses will 
not be an issue any more. Be careful with cables when connecting it however:
