A WiPod?

Is anyone at all surprised that the new AirPort Express is leading to tons of speculation that the next iPod will be wireless? If you're gonna wirelessly stream music to an AirPort Express it probably makes just as much sense to do it from an iPod as it does from an iBook. The only unknown about a WiPod is whether you'd be able to wirelessly swap music between them. Probably not, given Apple's reluctance to rile up the recording industry, but it's not like there is some major technical hurdle they'd have to cross to make something like this possible. Imagine being able to browse the collections on other people's iPods while riding the subway and trying to figure out which weirdo has the complete Four Non-Blondes discography.
