Stream music from Zune to Zune wirelessly -- not how you think

Props to Zunerama for an anti-hack so painfully obvious we're kind of kicking ourselves for not having thought of it before. Want to live stream your music to your pals with Zunes (what do you mean your pals don't have Zunes?) or even FM radios? Just use the FM transmitter. It's relatively low-powered, of course (unless you performed that other hack), but at least anyone who happens to know you're broadcasting on that particular frequency can listen in. Of course, it would be nice if they actually added this feature via WiFi so you could get nearby Zune discovery, track information, and all the fun stuff that makes us pissed about having to resort to such a silly hack as this.
