I've not used AHK, so cannot really comment on its capabilities.

From what I hear and see, around here.
If you're comfortable with scripting, Hot Key Net can do most of what IS Boxer can do.
But IS Boxer is the program with the most features.

Can you make a "Repeater Region"?
- an area where mouse broadcasting is enabled, while your mouse is in the area...
- useful for sending clicks to your healer, over a Grid/Vuhdo/Healbot frame... to heal from any toon.

Can you do round-robin effects?
- where you press the key once, and mage 1 does Polymorph.
- and on the next press, mage 2 does the polymorph.
- etc

Can you do "Send Next Click"?
- Press "2" (or whatever you put your Blizzard/Hurricane/Death & Decay on).
- Have AHK mirror your mouse on the slave window, but not send the click to the main window.
- Have it auto turn off the mouse broadcast once you click.

Can you click icons, and have those execute mapped keys?

Can you make mapped keys?
- a hotkey to execute them
- An action such as a spell, macro, enable/disable a keybind?

Can you view discreet areas of the slaves screens on the main's screen (Video Feeds) ?



Not sure if you "need" any of that.
Or what is available and what is not.
