The other USB storage-attachable routers I've seen don't seem to do it. Can I use the 500g as a wireless client, and provide internet access to devices ethernetted to it?

I'd like to use it portably, take it out to a wifi hotspot, and connect my packet8 VoIP phone.

Also, to hijack my own thread,
I have a PDA and a USB HD enclosure. I want to know if there's any way I
can take all of this out to a wireless hotpoint and access both the internet
and the 500g-attached storage at the same time.
