who mentioned the wow mouse??
I was discussing this thread with some people and one of them mentioned that the WoW mouse works like he thinks you're describing, and that Vyndree reviewed it and suggested that it was unreliable. So I offered the comparison based on the similarity.

I can see valid reasons outside of WoW, and I'd personally fall on the side that would say using a "typing a macro" feature is out of line based on my interpretation of WoW multiboxing guidelines, but Blizzard actively promotes the WoW Mouse which apparently works that way so who knows. My initial reaction is that you're making an assumption about the state of the game when those keys get pressed, so if someone happened to be typing in the chat window at the time, now they automatically send a line of chat like "hold on i need to kill this boss/focus joe" whereas sending a single key would, at worst, add a single character and not automatically press enter Or they're holding W move forward and the macro happens to include a W. Stuff like that. It's too easy to screw up, that's all I'm suggesting -- implement it if you like, it would be useful to various people.
and lax, i've never run is, so i have no idea what you're doing. legal? if you're making a wow macro that would require a wow reload, then its prolly within the lines.
You wouldn't have to run IS -- ISBoxer is generating a WoW Addon that creates macros (and would indeed require a WoW reload e.g. /console reloadui to make macro changes), and I don't think anyone has offered an interpretation that it is outside the lines.
