Thermistor connection

The easy solution for me is to just record the voltage outcomes, build a table and make conclusions of temperature based on the voltage outcome.

However, is there anyway of making the connection to the thermistor a switched one?

Is there anyway, I can have the thermistor cable go to two locations, even if only one could access it at any one time?
(and if this is the case, couldn't that be electrically switched some how)?

1 thermistor - 2 devices using it..

What would happen if I joined two wires at the device end of the thermistor and tried to get resistance measurements (i.e. the thermistor is still attached to the controller, that's powered on, and I've got some cable from the arduino to the controller's thermistor joint)?

Would that work, or would having the resistors there fry something?
