Can Bravado's Blade be performed with a throwing weapon?

[Cav5150]

Rake archetype for Rogue:

Bravado’s Blade (Ex)

When a rake hits an opponent and deals sneak attack damage, she can forgo 1d6 points of that damage and make a free Intimidate check to demoralize the foe. For every additional 1d6 points of sneak attack damage she forgoes, she receives a +5 circumstance bonus on this check.

This ability replaces trapfinding.

It doesn't explicitly state it must be a melee attack, can my rogue use this against an opponent who is flat-footed and vulnerable to sneak attacks?

Looks that way. Not sure how it fluffs out, but . . . yes?

[Davor]

Yes.

[StreamOfTheSky]

Yes, it works with any ranged attack as well as with melee. Intimidate still requires being within 30 ft, though so does sneak attack.
