Universal Follower Framework sounds like a COBL for followers. If so, this is really exciting. 

Yep.
At any rate, I think I've made my case for UFF as best as I can, and explained what the purpose of it is as fully as I can.
Current planned functions:
IsFollower() ;True if this actor is a follower; false otherwise.GetFollowerAtIndex() ;Returns the follower in the UFF's internal master follower array at the specified index..GetFollowerCount() ;Returns the number of followers currently in service.GetClosestFollower() ;Returns the closest follower from the given x, y, z position.GetClosestFollowerFromRef() ;Returns the closest follower from the given reference, optionally supplying a radius to search in.FollowerAction() ;Send the follower a command like "Wait here", "Follow me", "Trade", "Attack", using that follower's specific implementationFollowerSupports() ;Returns true or false, whether or not this follower supports this particular action. This one might be reaching a bit, but hey, I can dream.SummonAllFollowers(bInstant = false) ;Sends a command to all followers registered by the UFF to "Follow Me" and walk / run to the player. Setting bInstant will make them teleport to the player immediately.
Help me expand this library! I'd like further discussion to be towards what sorts of functions you'd like to have available in this API, as that was the primary reason I made this thread. Hint: If your comment doesn't contain a function suggestion, or a question about a function, you're probably not on-topic.
