Remember when WiFi base stations were just wireless base stations? The Asus WL-700gE WiFi router is more than just a base station. I has a built in 160GB drive, a iTunes client (daap, I assume), and a BitTorrent client, that can download directly to the device. Also if another drive is connected, it can be configured as a RAID.
The product web page states
iPod Users can Manage Music Stored in the WL-700gE with the iTunes Interface
I wonder how this works. Normally iPods will only sync with local files, and not with files through the daap protocol. Maybe if you connect an iPod directly to the WL-700gE with USB, you can go to a web interface to select files to be transferred to the iPod.
