USB HD attached to Z! Options

Since SL-6000 has USB host, is that possible to attach USB DVD?

I'd be interested to see someone reincarnate Toshiba's abortive "Bluetooth Pocket Server" (do a google search) idea from a couple of years ago -- one of these 5-10-20GB Toshiba HDDs with a small rechargeable battery, and Bluetooth. I think they actually marketed a batch of these, but it flopped fairly quickly. In principle it seems like a nice storage solution for a Bluetooth-equipped Z. Then you just keep the thing in your backpack and presto -- lots of available storage.

There's a rumor that Apple (or one of it's competitors) is going to build something like this into the next version of the IPod, with stereo Bluetooth wireless headphones. (Though don't hold your breath.) Obviously the throughput would not be great, but probably good enough for reading audio (though not video, which would be part of the attraction).

Anybody know of such a device? Seems like a natural extension to e.g. a digital camera (too slow to write directly, but camera could slowly migrate data from its primary storage card onto the remote HDD) but if Toshiba's experience is indicative it seems to be a product category that has already failed.
