8. The method of claim 7 wherein the adjusting comprises adjusting the device-specific ranking of the plurality of transports supported by the target device based on one or more of the following:

a size of a payload of the first message, including the command information, to be delivered to the target device;

whether communication of a payload of the first message, including the command information, to the target device involves communication of audio or video signals;

whether performance, by the target device, of the command involves communication of audio or video signals; and

any latency requirements for communication of the command information to the target device.

9. The method of claim 1 and further comprising:

adjusting the device-specific ranking of the plurality of transports supported by the target device based on one or more of the following;

a success rate in sending messages from the intermediary to one or more of the devices via one or more of the transports; and

current availability of one or more of the transports.

10. The method of claim 1 and further comprising:

determining that a size of the second message, including the command information, is greater than a threshold;

adjusting the device-specific ranking of the plurality of transports supported by the target device to favor one or more transports that are capable of handling messages greater than the threshold.

11. The method of claim 1 and further comprising:

determining that the command information is requesting audio or video data services;

adjusting the device-specific ranking of the plurality of transports supported by the target device to favor one or more transports that are capable of providing audio or video data delivery or streaming services.

12. The method of claim 1 wherein the transport supported by the client application comprises a communications protocol supported by the client application.

13. The method of claim 1 wherein the transport supported by the target device comprises a communications protocol supported by the target device.

14. A computer-implemented method for executing instructions stored on a non-transitory computer-readable storage medium, the method comprising:

receiving, by the intermediary from a client application associated with a user account, a first message sent via a transport supported by the client application, the first message including a device identifier to identify a target device of a plurality of registered devices, a command information identifying a command that is supported by the target device and to be performed by the target device, and a response maximum wait time field that identifies a maximum wait time before the intermediary will send a response to the client application in response to receiving the first message;

identifying, by the intermediary based on a stored device registration information for the target device, a transport supported by the target device;

sending, by the intermediary to the target device via the identified transport supported by the target device, a second message including at least the command information; and

sending, by the intermediary to the client application at a time not later than a time indicated by the response maximum wait time field, a response to the first message that includes at least a command status that identifies a status of a performance of the command by the target device.
