I'd love an Ethernet shield in general. In this case, however, the pc is always on as I use it for a media/web/email/etc server. It doesn't matter to me whether it's tethered to the server or a switch. I like finding new uses for the server anyway, since it has a lot of idle cycles. If the shield had power-over-ethernet that allowed me to eliminate the wall wart, I'd have to consider it though. I guess I'd then have to buy the shield and a PoE switch. I'm sorta broke.
