A2DP support is currently on the official Maemo roadmap. I know a lot of people have been eager for its implementation as it would greatly enhance the VOIP and multimedia playback capabilities of the N800. I am very hesitant to recommend you simply wait, though, as Nokia has been consistently very slow to add new features to the platform. There has been some speculation that the update with Skype support is coming out in the VERY near future and A2DP support would be a logical feature to add at the same time. There was a major pissing match over speculation that it might even be tomorrow. My advice is to wait a week or two and see. If it hasn't come out by then, go buy yourself some A2DP headsets that comes with a bluetooth audio dongle to plug into the N800's 1/8" stereo port.
