A Surprise Attack should be defined as one in which you enter your opponent's territory or attack him on the same turn you declare a war. A civilized leader will give his opponent a modestly sporting chance to gather his forces (probably to have one large battle and crush him), while a dastardly leader will begin a war by attacking.
In this game, surprise attacks seem extremely powerful. Gather forces near cities with shortened borders, declare war, attack, take 2-5 cities at once, and in that amount of time, they want to capitulate. I have had wars last 2 turns, including the turn I declared it, and losing 2-5 cities the first 2 turns of a war seems frightfully disadvantageous.
While there is already a diplo-penalty for "attacking my friend", this doesn't seem to go far enough. An extra diplo-penalty if the DoW included surprise attacks, with further penalties for each city you attack or take on the first 2-3 turns of the war. Extra war weariness for any units you kill or lose in those opening turns, since diplo-penalties seem out of proportion for such. Alternately, WW could be accrued even from battles on home turf, since a surprise attack was a surprise to everyone.
The diplo-penalties might begin, or become bigger once Nationalism is researched, or against a Civ using it.
Alternately, instead of a diplo-penalty, your power rating might be significantly diminished (-20%?), making you a more attractive target for opportunistic civs, and even dogpiles if you do enough Surprise Attacks, or your relations suck enough, though this would function more as a retribution attack than a "all your troops are gone" attack.
Naturally, such surprise attacks won't affect civs who've never heard of you, so you can probably still get away with it in the early game, and in the late game when you're already powerful enough to take on the world, it won't matter much then anyway.
