Empty quiver flexibility and threatening squares

[mrofmist]

So, this feat chain has been picked apart and questioned in every way. One part has me uncertain though.

With flexibility you threaten adjacent squares, is this threatening with a melee attack, or a ranged attack? I would assume the AoO needs to be melee, but it isn't specified so I'm curious what other people have interpreted this as.

With a melee attack as per empty quiver style. It is an extension of that feat.

That's what I figured, and after looking back at the first feat I assumed so.

Now, another one I thought of, which we had a hard time coming up with an answer for last night. How does the PC swing the bow? Is it a two handed attack? It's a heavy mace, so a one handed weapon, but a bow is a two handed weapon. Is it reasonable to assume the PC would also swing it two handed? Not going to be using a shield anyways. So it seems reasonable.
