Here it is, the MZ-04G, LAN router sold by Planex which, over the usual features of a Gigabit Ethernet Router, comes equipped with a USB port allowing you to plug in an external HDD (turning it all into an NAS, PS3 compatible).
You can use it as a little server for iTunes or Bit Torrent, from there you may get to meet the people of the RIAA if you live in the United States, if you don’t, just don’t worry about it.
