For those who really really want partial follower functionality with Dragonborn and UFO right now, here is a quick fix:
https://dl.dropbox.com/u/986370/Drag...miss%20Fix.zip
Drop the files into data/scripts (or use NMM). If the mod author objects, I can take down the link. It is only an edit of DB .psc files, not UFO. This will probably NOT allow for multiple follower functionality or any of UFO's features, and I haven't tested the "wait here" command. It will, however, allow you to hire and dismiss the DragonBorn followers, as long as you do not have any vanilla followers following you. Vanilla follower functionality is unaffected. If you already hired a follower in DB with UFO active, it should let you dismiss him/her, but you might also need to reset PlayerFollowerCount manually once (see tech details for why).
REMOVE these files once an official UFO patch appears!
Tech details: The only changes are: adding an extra argument to DialogueFollowerScript.DismissFollower() with the follower's reference, which UFO uses to dismiss the correct follower, and removing forceful setting of PlayerFollowerCount to 1 (which caused a double count since UFO increments it again). Source included.
