You could add a keybind in dwm/wmii to call XGrabPointer to toggle a
lock on the currently focused window. Since it's only grabbing the
pointer, dwm/wmii will still be able to read the key to ungrab.

I've attached code for dwm anyway.

config.h:
{ MODKEY, XK_l, pointerlock, { .i = 1 } },
{ MODKEY|ShiftMask, XK_l, pointerlock, { .i = 0 } },
