Thank you for your replies. I'm looking to do this with AutoHotkey, as my main computer is quite fast. (64 x2 4600+, 2GB RAM, 10K RAID 0, 8800GTS). I've gotten both characters up, and it doesn't feel sluggish. Also, I've had some simple success with AHK (both toons jumping).

How do you transmit the mouse clicks and coords through AHK?
