5. The first controlling device according to claim 1 , wherein the processor is operative to delay granting access to the second controlling device by a certain delay so that the control commands received from the second controlling device will be timed to be interspersed with the wirelessly sending the control commands to the remote device by the processor.

6. A second controlling device comprising: a processor; a memory to store data used by the processor; and a user input interface, wherein the processor is operative to:

wirelessly send a first pairing request to a remote device;

in response to receiving the denial, wirelessly send a second pairing request to the first controlling device;

wirelessly receive a grant of access from the first controlling device;

receive user input commands from the user input interface for controlling the remote device; and

wirelessly send control commands to the first controlling device for controlling the remote device based on the user input commands from the user input interface.

7. The second controlling device according to claim 6 , wherein, after the first controlling device loses a connection with the remote device, the processor is operative to wirelessly:

in response to losing the connection, send a third pairing request to the remote device;

receive a grant of access from the remote device; and

send control commands to the remote device for controlling the remote device based on the user input commands from the user input interface.

8. The second controlling device according to claim 7 , wherein the processor is operative to wirelessly:

receive a fourth pairing request from the first controlling device;

grant access to the first controlling device;

receive control commands from the first controlling device for controlling the remote device; and

send control commands to the remote device for controlling the remote device based on the control commands received from the first controlling device and the user input commands from the user input interface.

9. The second controlling device according to claim 6 , wherein the processor is operative to wirelessly:

receive a fifth pairing request from a third controlling device;

grant access to the third controlling device;

receive control commands from the third controlling device for controlling the remote device; and

send control commands to the first controlling device for controlling the remote device based on the control commands received from the third controlling device and the user input commands from the user input interface.

10. The second controlling device according to claim 6 , wherein the user input interface is operative to receive the user input commands from a pointing device.

11. The second controlling device according to claim 6 , wherein after the processor has received the grant of access from the first controlling device, the processor is operative to send the control commands to the first controlling device for controlling the remote device at a higher frequency than if the second controlling device was sending the control commands directly to the remote device and not via the first controlling device.

12. The second controlling device according to claim 6 , wherein while the second controlling device has access to the first controlling device, the processor is operative to only send signals to the first controlling device when one of the user input commands is received from the user input interface.

13. The second controlling device according to claim 6 , wherein after the processor has received the grant of access from the first controlling device, the processor is operative to time sending the control commands to the first controlling device for controlling the remote device to be interspersed with a plurality of control commands wirelessly sent from the first controlling device to the remote device.

14. An apparatus comprising: a processor; and a memory to store data used by the processor, wherein the processor is operative to wirelessly:
