yeah, it's possible. Probably more expensive than it's worth. You couldn't make it jam-proof really. Anyone nearby with a really strong transmitter could always jam it, if they used the right frequency. You could make it really hard to jam, but never impossible.
The hacked part is much simpler. Just code each transmitter/receiver pair to each other using a semi-secure protocol.
