Its a matter of setting up your party bar in the exact same place and order on all clients and using hotkeynet to broadcast right/left/middle clicks which are set to cast skills in clique.

Works very well allowing you to heal anyone without breaking the main's target to having excessive healing macros for each character.

Only problem I've run into is when I dont get put in the same party in battlegrounds, I'm sure there is a way around this though I just haven't played with it much.
