I use healbot on my main holy pally, but I was thinking it's be way cool if I could move the healbot window from one instance of wow to another, i.e use the click cast heals from healbot from my tank. I know it won't work exactly like that, but if I could somehow get healbot modified to redifect the cast to the healer, it would help me out immensely. Then I could use the main keys to control my tank and maintain aggro, use hotkeys for dps, and click cast heals to whoever needs em, without taking up hotbar space.

Is this possible? Seems like it would make 5 class 5boxing easier to manage.
