This might sound a bit dumb, but I was wondering—in Finder's sidebar every network share shows up with the corresponding icon, my Mini has a Mini icon, my Macbook a Macbook icon and so on and so forth. Generic (unidentified?) shares just show a simple display icon, SMB shares even had a BSOD icon back in Leopard. My question is, how does this exactly work? Does the share "announce" the Model Identifier?
