For the rest of us the only real possibility would be to make
an app that uses the hardware sensors of the n900
to sniff out females who are in heat.

I think we might need to hack in an IR sensor and
we could probably use the FM receiver application
as a form of reflectivity-mapping using the wifi transmitter
to generate (fm-band) rf body maps which could be digitally
analyzed for blood-flow and warm (moist) spot volume.
Combine that with an audio voice-stress analysis package
and we would be 'good to go'...

Anyone here remember a thing called the 'tricorder'?
