Take a look at Model 4353 here: http://www.zoom.com/products/ihifi.html

I want to use this to stream audio from the N800's headphone jack to my stereo equipped with the bluetooth receiver. My worry is that the thing will cover the power jack. It would still work on batteries, but that would be annoying to have to stop every few hours to recharge. Eventually maybe we will have a2dp, but until then.....
