Is it possible to have my MacBook become an iBeacon?

Is it possible to have my MacBook become an iBeacon ? I would like it to broadcast itself to iOS devices which support iBeacons. If this is possible, what are the hardware requirements of the computer (e.g. is Bluetooth 4.0 enough?), and how would I do it? **Update**: I am primarily looking for a way to do this without any additional hardware (since my MacBook already has Bluetooth built-in).
