Skin!!!!
Excellent question, excellent. (wiping drool off the keyboard and chin as I type)
Last year I did a dozen or so whole roasting pigs in my "Mistress" (MeadowCreek TS250 reverse flow) using primarily charcoal and hickory splits. Smoking/bbq-ing a whole roaster you don't necessarily have to worry so much about over-smoking, having the entire beast in there with all the skin protects that meat wonderfully.
The skin results from my pig roasts usually have a very strong smoke taste, almost on the border of too much. Some folks have nibbled, some folks have passed, the damned ears almost always get donated to someone's very lucky dog.
I've been looking for someone with a commercial deep frier they'd be willing to smoke up their grease in by deep-frying some of the smoke pig skin. No takers yet.
OK, enough back ground... my point is, I've done chicken, turkey legs, Boston Butt-shoulder, and beef chuck roasts in my Flat Top UDS. I'm having a hard time seeing "over smoking" in a UDS, you'd have to really use some green wood or wet wood to do it, IMHO.
As well, the UDS gave that "flame broiled" flavor along with the smoke to all the meats I've done so far.
Now that you mention the skin I'm hoping it'll have that same flame broiled, light smoke flavor every thing else has. I've got an electric deep frier sitting loaded with peanut oil just begging me to deep fry some pork skin.
I realize smoking, low and slow, like this is not the same process they use to make pork rinds available in stores as snacks. But it's close enough I've often wondered what taking that smoked skin and frying it would produce.
Perhaps I'll be extending this thread with some Deep Fried BBQ Pron later?
