I love Scottish beers, though I can't say I have much experience brewing them. I've tasted some that used low/moderate levels of peat smoked malts that were quite tasty.
Regarding peat malt, beer historian Ron Pattinson has said many times that there's no evidence that peat was historically used in the production of malt for beer, but that is was used in areas where malt was produced for whiskey, hence confusion and colorful reinvention of history. I don't know if other beer historians agree or not.
