Using BLE for Data Streaming

[kapilv]

Does there exist any commercial device in market that uses BLE for data streaming? Is it feasible? Are there any API's to develop such a product?

Sorry for the confusion. By "any device" I meant atleast one device. It should be streaming BLE data to some device which is able to recover the data and display it somehow(better if the data is audio).

I would like to stream data between two devices then cut-off the power to one device and see how the other one reacts by observing its packet on a packet sniffer. If the devices are commercially available that would be great.
