The FCC just approved Nikon's WiFi adapter for the D200. It may be a bit big, but I still want one.

Also, while perusing the manual for the adapter, I noticed that in addition to it's wifi goodness, the adapter also has a shutter release button that makes it easier to use the camera when shooting in a portrait orientation.

Sweet! That will be very useful for those tripod moments.
