Took me a while to figure it out too, and this is what I eventually came up with

<Command LaunchAndRename>

<SendPC Local>
<Run "e:\Games\World of Warcraft\WoW.exe">
<RenameTargetWin WoW1>
<SendWin WoW1>
<Wait 200>
<Text USERNAME>
<Wait 200>
<Key Tab>
<Wait 200>
<Text PASSWORD>
<Wait 200>
<Key Enter>

<SendPC Local>
<Run "e:\Games\WoWclone\WoW.exe">
<RenameTargetWin WoW2>
<SendWin WoW2>
<Wait 200>
<Text USERNAME>
<Wait 200>
<Key Tab>
<Wait 200>
<Text PASSWORD>
<Wait 200>
<Key Enter>

<SendPC Local>
<Run "e:\Games\WoWclone\WoW.exe">
<RenameTargetWin WoW3>
<SendWin WoW3>
<Wait 200>
<Text USERNAME>
<Wait 200>
<Key Tab>
<Wait 200>
<Text PASSWORD>
<Wait 200>
<Key Enter>

<SendPC 192.168.1.3>
<Run "C:\World of Warcraft\WoW.exe">
<RenameTargetWin WoW4>
<SendWin WoW4>
<Wait 200>
<Text USERNAME>
<Wait 200>
<Key Tab>
<Wait 200>
<Text PASSWORD>
<Wait 200>
<Key Enter>

<SendPC 192.168.1.3>
<Run "C:\World of Warcraft\WoW.exe">
<RenameTargetWin WoW5>
<SendWin WoW5>
<Wait 200>
<Text USERNAME>
<Wait 200>
<Key Tab>
<Wait 200>
<Text PASSWORD>
<Wait 200>
<Key Enter>

Then just set the <LaunchAndRename> command a Hotkey:

<Hotkey Numlockon Alt Ctrl L>
<LaunchAndRename>
