One Dexcom G4 sensor and transmitter, two receivers? Anyone had experience?

This is not a crude attempt at a joke.. ;-) Anyway. I am currently wearing a Dexcom G4 sensor and transmitter. I have it paired to one transmitter, but for reasons I won't go into because it's a long and complex story, I would like to pair another receiver to it. Has anyone done this before? In theory, I could just put the serial number of the transmitter into the second receiver and it would just pick it up in addition to the other receiver. Both would calibrate differently, etc. In theory each receiver would just act like they were the only one since there is no two way communication between transmitters and receivers that I know of.
