To use the Ethernet in the car you would have to modify the sled, you can get a little hint of how this could be done at http://427.org/album.asp?AlbumID=3

Plenty of people have done this for their own home docking stations, if you plan to mount it else where in the car I can recommend mlord's docks (I'm going to have to start charging for these adverts Mark ) That has Ethernet access built into the dock.

Mazda RX8 WOW !!! I've got an old 323F (1997) Not much room in these Mazdas for mods how are you going to fit it all in ???

Cheers
