two runners, two nike+ systems - will they interfere with one another?

[je55ica]

I'm planning on running with a friend. We both have the nike+ system.

So, two runners, two nike+ sensors, two nike+ receivers and two ipod nanos.

Will our nike+ systems interfere with one another? For example, will my ipod start picking up her data or data from both of the sensors? Has anyone had this happen?

Thank you.
