Theoretically it sounds like it'll work. Care to explain in more detail? Perhaps write a tutorial yourself?
Any program required?
Dual client isn't an issue, but how would the rest work?
I assume you set one client to continually shoot whilst the other continually throws ammo, correct?
EDIT: If there is a program that allows for auto mouse clicker + key presser that specifically bind to applications, then I have figured out a strategy and am willing to test and post results. Just need program.
