1. A method usable with a well, comprising: communicating a wireless stimulus in the well, the wireless stimulus being indicative of a command;actuating a multi-position valve in response to the communication, the valve having more than one controllable open position;confirming downhole in the well
1. A method usable with a well, comprising: communicating a wireless stimulus in the well, the wireless stimulus being indicative of a command;actuating a multi-position valve in response to the communication, the valve having more than one controllable open position;confirming downhole in the well whether the valve has operated in accordance with the command; andacknowledging whether the valve has been operated in accordance with the command, comprising using a transducer for the valve that is located proximate to an exterior surface of downhole production tubing to communicate another wireless stimulus from the valve uphole to identify that the operation of the valve has been confirmed downhole. 2. The method of claim 1, wherein the actuating comprises communicating with a variable orifice sleeve valve. 3. The method of claim 1, further comprising: communicating said wireless stimulus to the surface of the well. 4. The method of claim 1, wherein said another wireless signal is indicative of a position of the valve. 5. The method of claim 1, wherein the communicating comprises: transmitting an electromagnetic wave from the surface of the well through at least one subterranean formation. 6. The method of claim 1, wherein the communicating comprises: communicating a seismic wave from the surface of the well through at least one subterranean formation. 7. The method of claim 1, wherein the communicating comprises: communicating an acoustic wave downhole. 8. The method of claim 7, further comprising: communicating the acoustic wave on a tubular string. 9. The method of claim 1, wherein the communicating comprises: communicating a pressure pulse downhole. 10. The method of claim 9, further comprising: communicating the pressure pulse through at least one of a fluid in the production tubing or a fluid in an annulus. 11. The method of claim 1, further comprising: encoding the stimulus to indicate a command; anddecoding the stimulus near the tool to extract the command. 12. A system usable with a well, comprising: a multi-position valve located downhole in the well, the valve having more than one controllable open position;an apparatus to communicate a wireless stimulus to the tool to actuate the valve, the wireless stimulus being indicative of a command;a transducer located proximate to an exterior surface of production tubing comprising the valve; anda circuit located downhole to confirm the command, operate the valve in accordance with the command, and use the transducer to communicate another wireless stimulus uphole to acknowledge that the valve has been operated in accordance with the command to identify that the circuit confirmed the command. 13. The system of claim 12, wherein the valve comprises a variable orifice sleeve valve. 14. The system of claim 12, wherein the valve is adapted to communicate said another wireless stimulus to the surface of the well. 15. The system of claim 12, wherein said another wireless stimulus indicates a position of the valve. 16. The system of claim 12, wherein the apparatus is adapted to transmit an electromagnetic wave from the surface to the valve through at least one subterranean formation. 17. The system of claim 12, wherein the apparatus is adapted to communicate a seismic wave from the surface through at least one subterranean formation. 18. The system of claim 12, wherein the apparatus is adapted to communicate an acoustic wave downhole to actuate the valve. 19. The system of claim 18, wherein said apparatus is further adapted to communicate the acoustic wave using a tubular string. 20. The system of claim 12, where the apparatus is adapted to communicate a pressure pulse downhole to actuate the valve. 21. The system of claim 20, wherein the apparatus is further adapted to communicate the pressure pulse through one of a fluid in the production tubing and a fluid in an annulus. 22. The system of claim 12, wherein the apparatus is further adapted to: encode the stimulus to indicate a command, anddecode the stimulus near the tool to extract the command. 23. A method usable with a well, comprising: communicating a wireless stimulus in the well, the wireless stimulus being indicative of a command;actuating a multi-position valve in response to the communication, the valve having more than one controllable open position;confirming downhole in the well whether the valve has operated in accordance with the command; andacknowledging whether the valve has been operated in accordance with the command, comprising using a transducer for the valve that is located proximate to an interior surface of downhole production tubing to communicate another wireless stimulus from the valve uphole to identify that the operation of the valve has been confirmed downhole. 24. A system usable with a well, comprising: a multi-position valve located downhole in the well, the valve having more than one controllable open position;an apparatus to communicate a wireless stimulus to the tool to actuate the valve, the wireless stimulus being indicative of a command;a transducer located proximate to an interior surface of production tubing comprising the valve; anda circuit located downhole to confirm the command, operate the valve in accordance with the command, and use the transducer to communicate another wireless stimulus uphole to acknowledge that the valve has been operated in accordance with the command to identify that the circuit confirmed the command.
