Yeah, I've managed to get a Linux box to recognize the Command key as super when I plug in an Apple keyboard. Some apps seems to look for actual scancodes, though, rather than for what X11 tells them the mappings should be. My experience was pretty hit or miss, and mostly I ended up with an mismash of semi-random keybindings which is sort of the opposite of what I was shooting for. On the Mac developers have done a remarkably good job of adhering to a consistent set of shortcuts (down to things like Command-, for preferences). The other issue is that most apps don't make it straightforward to bulk re-assign keybindings from Control to Super, and last I checked it was impossible to turn off menu accelerators for Gtk+ based apps (e.g., Alt+F to bring up the file menu in Firefox). Most of the time what I want is to map Command->Super and Option->Meta, and have Super replace Control in all GUI app keyboard shortcuts leaving Control available for command-line apps, in general.
