Okay so this thread is 3 years old now, but I had recently been exploring this sort of "formation" movement myself. I thought you could use mouse clicks in conjunction with click-to-move on the slaves to do it but so far haven't had any luck. So far, I've tried the following:

Code:
<Hotkey ScrollLockOn Oem1>
    <SendLabel w2>
        <ClickMouse RButton Both Window 50% 50%>
    <SendLabel w3>
        <ClickMouse RButton Both Window 45% 50%>
    <SendLabel w4>
        <ClickMouse RButton Both Window 55% 50%>
    <SendLabel w5>
        <ClickMouse RButton Both Window 60% 50%>
Which doesn't seem to do anything at all, actually. That is, I press the key, HotkeyNet picks it up and apparently executes the macro, but I don't see any sort of response in my slave windows. Based on this thread, it looks like most people just use key movement, but I thought you could make for more interesting formations using click-to-move. I've tried moving the 1st value around a bit to make sure i wasn't clicking too close to the center to cause it to move. Any suggestions as to what I might be doing wrong?
