I use AHK as well and run 2 warlocks on a single PC. I haven't made a "spread out thingie" yet, but will be adding one soon.

I'll add the script once I get it written out (when I get home tonight) but the theory would work like this...

Set a Key in AHK script to send one key press to WoW1 and a differant key press to WoW2.

Example:
W = WoW1 (move up) AND WoW2 (move back)
S = WoW1 (move back) AND WoW2 (move up)
A = WoW1 (move left) AND WoW2 (move right)
D = WoW1 (move right) AND WoW2 (move left)

This will get your toons to move apart in the Axis you want and then back together in the Axis you want.
