External Wireless Microphone for Nikon D90?

Yes probably all of you would say there can't be external mic

or half of you would say zoom h2.

But neither of them would fill my need.
Is there any wireless microphone that records the audio to somewhere. Like zoom h2, But the recorder and mic is wireless.

I was just googling and came across this product hope it helps you
