Throwing short swords?

[Diminutive Titan]

I was wondering if the Throw Anything feat applied only to "improvised weapons" or if it also applies to "weapons that are not normally designed to be thrown"?

The Feat:
Throw Anything (Combat)
You are used to throwing things you have on hand.

Benefit: You do not suffer any penalties for using an improvised ranged weapon. You receive a +1 circumstance bonus on attack rolls made with thrown splash weapons.

Normal: You take a –4 penalty on attack rolls made with an improvised weapon.

From the Weapons section:

It is possible to throw a weapon that isn't designed to be thrown (that is, a melee weapon that doesn't have a numeric entry in the Range column on Table: Weapons), and a character who does so takes a –4 penalty on the attack roll. Throwing a light or one-handed weapon is a standard action, while throwing a two-handed weapon is a full-round action. Regardless of the type of weapon, such an attack scores a threat only on a natural 20 and deals double damage on a critical hit. Such a weapon has a range increment of 10 feet.

Suppose I took the Throw Anything feat followed by Distance Thrower, would that mean that as a standard action I could throw a short sword up to a distance of 20 feet without penalty?

Or does the -4 still apply since the shortsword isn't actually a "improvised weapon" but is rather a "weapon that is not meant to be thrown"?

If you really want to throw a shortsword, get a magical shortsword with the throwing property and buy one of those scabbards that lets thrown weapons return to you after they hit.

The drow of eberron had a throwing short sword (D&D 3.5). But I would say all you need is throw anything feat, then use your standard action. With the distance thrower would indeed get 20' with no other penalties. That is how I read it.
