LaCie upgrade NAS to Home Edition with online sharing interface
Back when I reviewed LaCie's Ethernet Disk mini I was particularly taken by its UPnP media funnelling capacities (which still form the core of my home media setup); now they've upgraded the range of compact network-attached storage with the Home Edition, which adds remote access, iTunes media server functionality and Axentra HipServ for drag'n'drop file sharing.
DLNA-compatible UPnP multimedia streaming and a new online LaCie interface should help you make the most of the 500GB storage, while the $199 price tag shouldn't break the bank.
It's available for pre-order now, and should ship in late October 2007.
