Well Volendrung with scripted ability return to hands of owner, such ability can be received as reward for doing some quest and fit lore also
Hammerfell's original name was Volenfell, given to it by the Rourken Clan of Dwemer during the First Era. It is said that the leader of the clan threw his mighty hammer, Volendrung, across the continent, and followed it to their new home (This scene is depicted on many frescos in Ruins throughout the region.) The Rourken were opposed to the creation of the joint Dwemer-Chimer state of Resdayn, which prompted their move westward. It was later named Hegathe by the Aldmer and Deathland by the Nedic peoples, before the Redguards arrived and named it Hammerfell, translated from the Dwemeris.
Return of throwing weapons will be great and many of us will agree with this.
Throwing weapons are not crossbows so will not looks outside of technology level in Skyrim (there is still can be an dwemeric artifact crossbow used as prototype for http://www.tesnexus.com/downloads/images/22684-2-1237587327.jpg),
Throwing weapons isn't hard to be done its utilize almost the same physique thats arrow have and was done with mods for Oblivion
http://www.youtube.com/watch?v=QzOsBAPoWQE in 2006 after few months after release of Oblivion completely on scripting and without OBSE
http://www.youtube.com/watch?v=2Yt_FdTIBeU&t=2m10s more advanced implementation uses OBSE and allow throwing of different items and certain weapons suit better for throwing like daggers and axes, throwing work as fully supported alternative to archery use attributes and marksman and train marksman skill on using, there is work collision detection so weapons bounce from stones and stick in wood.
So thee even no need create special throwing weapons normal arms can be used just need throwing system, once created it even can be usable for more combat oriented Telekinesis spell also so additionally there will be variability in damage dealing magic as positive side effect.
Throwing weapons will expand Marksman and make it more interesting and variable, why marksmans need relay only on bows when warriors have more then just swords and mages have more then one fire ball spell?
Work well with stealth alchemy as throwing flasks of Flammable Oils, Damage Equipment Acid, Slippery Grease, Poison and Paralyze Gas, Smoke or Flashbang Bombs etc.
Alchemy will be much more fortified as Stealth skill with more then just poisons, besides flaming oil confirmed already.
Add ability distract enemies guards with with throwing clutter around

Was also done before with mods, why not implement such feature in game and show thats AI become really good at this time, besides AI reacting on dropped items already confirmed so why not enhance it more?
Some throwing weapons can relay on
Agility and Marksman so poison needles and darts, stars and daggers, can be usable by nimble characters, some on
Strength and Marksman so powerful characters will not relay only on melee combat but also will have some options for short and middle distance like Throwing Axes, Javelins, Throwing Hammers, Stones for Giants
Traits and skills in two-handed and one-handed (dual wield) skills can be used if attributes was removed as well different weapons can burn different amount of Fatigue.
Throwing weapon isn't has the same purpose as bows have bows work middle-long distance need better targeting and usable for sniper and need time to be drawn, bows utilize both hands for work like two handed weapons
while Throwing weapon work on short-middle distance not need better targeting so there is no bow sway effect, usable for silent kills at short distance, take smaller time to draw, utilize dual wielding (we can throw two projective at one time) and even with some skills (perks) can give ability throw more weapons at one time thats anologue of dual wielding for marksman weapons.
No need different or special button for Throwing Grab Key can be used with Strike Button for current hand Simulationsly, hold it for some time and release will allow throw current equipped item forward, holding it more will allow thrown it furtherer, use just strike button will swing weapons as melee weapon, if throwing an clutter no need to show it in equipped in hand and quick tap of grab will drop item, while another quick tap will allow garb item again, no need hold button for dragging item around.
