The Xserver emits the keycodes & Keysyms. You can update these using
xmodmap. For instance, xev returns the following for my "window" key:
KeyPress event, serial 26, synthetic NO, window 0x1400002,
root 0x4a, subw 0x0, time 472295996, (106,126), root:(229,871),
state 0x0, keycode 115 (keysym 0x0, NoSymbol), same_screen YES,
XLookupString gives 0 characters: ""
Looking in /usr/X11R6/lib/X11/XKeysymDB it looks like there keysym's
IA1 .. IA15 and IB1 .. IB16 might be available (I don't know what they're
really meant for). Then I can map the keycode to a keysym with xmodmap
xmodmap -e 'keycode 115 = IA1 IB1'
And then for "window" and shift-"window":
KeyPress event, serial 26, synthetic NO, window 0x1400002,
root 0x4a, subw 0x0, time 472672129, (77,42), root:(200,787),
state 0x0, keycode 115 (keysym 0x10004101, IA1), same_screen YES,
XLookupString gives 0 characters: ""
KeyPress event, serial 26, synthetic NO, window 0x1400002,
root 0x4a, subw 0x0, time 472673806, (77,42), root:(200,787),
state 0x1, keycode 115 (keysym 0x10004201, IB1), same_screen YES,

Metacity might handle the modifier keys directly, so assiging
xmodmap -e 'keycode 115 = IA1'
might still allow <shift>IA1 and so on.
You'd have to put the xmodmap in a session startup file for that
workstation for it to have automatically have effect.
Looking in /etc/X11/xdm/Xsession, it looks like if you have a
/etc/X11/Xmodmap or $HOME/.Xmodmap file it will load that during
session startup. Read the xmodmap man page for more.
Haven't been able to test this with metacity - gnome doesn't support
multiscreen until gnome 2.2. But I hope this helps.
