Along the lines darylgo's comment, I was interested in getting the Logitech DiNovo mini to use over bluetooth with the dock but couldn't find anyone who had tried that setup. I didn't want to buy online just to have the hassle of returning it if it didn't work.
One Logitech setup I tried uses one of the older receivers that acts as a cradle for charging the mouse and the other is with the unifying receiver, wireless illuminated keyboard, and the marathon mouse. The kbs/mice were paired previously with their receivers and worked right away with the dock. Obviously with the unifying receiver you need the Logitech SW to use both with one receiver, so I don't think you can set up the receiver with the second device on the dock itself.
