I'm using Hotkeynet at this moment. With only pressing my numpad 7 my 5 toons make a diamond form.

<hotkey NUMPAD7>
<sendpc local>
<sendwin "World of Warcraft">
<keyDown W>
<sendpc 192.168.1.4>
<sendwinm WoW2>
<keyDown E>
<sendwinm WoW1>
<keyDown Q>
<sendpc 192.168.1.5>
<sendwinm WoW2>
<keyDown S>
<sendwinm WoW1>
<key w>

<hotkeyUp NUMPAD7>
<sendpc local>
<sendwin "World of Warcraft">
<keyUp W>
<sendpc 192.168.1.4>
<sendwinm WoW2>
<keyUp E>
<sendwinm WoW1>
<keyUp Q>
<sendpc 192.168.1.5>
<sendwinm WoW2>
<keyUp S>

For the WoW1 on the 192.168.1.5 i didnt use a KeyDown, just a single Key W tap so he dont keep follow my leader. ^^
