Lax:

When you say Clickboxing can send to x,y coords, does that mean regular pixel points within the resolution of the monitor? i.e. my WoW is maximized on the screen at 1600x1200, and you're basically just clicking a pixel at point 75,95 which happens to be where my Bar1 Key1 is?

Would this require you to have 1 monitor per WoW instance (and probably more then 1 computer)?

Or is this an x,y based upon the WoW window itself? i.e. My WoW is windowed to 1024x768 on my 1600x1200 monitor, and point 1,1 is the lower left corner of the current WoW window. Which would thereby allow multiple WoW windows on a machine. This is what it sounds like more to me, but I'd like clarification.
Also, as far as clicking a point in WoW (assuming it's multiple instances on 1 machine) how do you overcome the click once for focus of the window?

If it's not agianst the ToS/Blizzards bias towards your company's software, it sounds fantastic, as we can finally have back our click for blizzard/treants/rain of fire/flamestrike functionality without have to resort to multiple boxes and hardware replication.
