Throwing a Speed / Hasted Returning Weapon

[Sudiken]

I need help figuring out how a weapon with the speed and returning values would react being thrown during a full-attack action.

1. Would your weapon strike twice during the throw or would you lose the benefit of Speed or Haste entirely if you threw your weapon?

2. Also, if all your thrown weapons have the returning attribute and you throw multiple weapons with the Speed attribute, would you get double hits from each weapon that round?

:EDIT:
I guess this could also cover using Quick Draw with a handful of Speed weapons.

Speed
When making a full-attack action, the wielder of a speed weapon may make one extra attack with it. The attack uses the wielder's full base attack bonus, plus any modifiers appropriate to the situation.

By the base description it would appear that if you use multiple weapons during your attack that each individual weapon with the speed attribute would receive an extra swing.

Thanks for the replies :)

You wouldn't get multiple attacks with a speed returning weapon because

This special ability can only be placed on a weapon that can be thrown. A returning weapon flies through the air back to the creature that threw it. It returns to the thrower just before the creature's next turn (and is therefore ready to use again in that turn). Catching a returning weapon when it comes back is a free action. If the character can't catch it, or if the character has moved since throwing it, the weapon drops to the ground in the square from which it was thrown.

Emphasis is mine. Since it returns just before your next turn it can't be used in the same turn.

What you could do with a speed weapon is make a regular melee attack with it and THEN throw it as the speed attack.

Or use a blink back belt

Thanks guys, I was just wondering because I knew the rule of returning during your next turn but I was unsure how that related Speed or Haste. Everything about throwing weapons seems to go against the grains of feasibility vs. other options.
