Is there a way to click on a macro on my main toon that will send a command to my alts?

What I want to do is click on a custom macro that will make my alt mages cast arcane explosion (without using keybind)...
Some things can be relayed between your toons via whispers or in group chat. Follow is an example that works, and there are several UI mods out that will cause your toon to follow on command. Casting a spell is another matter.

UseAction(slot[, checkCursor[, onSelf]]) for example is a protected API. It can only be called from a Blizzard signed UI.
