Given that Flurry of Maneuvers in the Maneuver Master archetype replaces Flurry of Blows, can a Maneuver Master take Two-Weapon Fighting normally to get two attacks, and still be able to make his free extra maneuver as per Flurry of Blows, possibly getting three trip attacks or disarms attempts in one round?
Yes, it looks like this works fine.
Do you know what has never been worth doing in one round, though? Three trip or disarm attempts. ;)
It is with a reach weapon, which monks have several of.
Forgive me, but where are these weapons in the monk's list of weapons, that they can flurry with? I know there are a few reach monk weapons, but they require an Exotic Weapon Proficiency feat to use.
It also depends how many foes you fight, and who they are.
DM: "The gargoyles swoop down and attack you!"
Monk Player: "I trip them as they rush me!"
DM: "They are flying."
Monk Player: "OK, I sisarm them"
DM: "They have natural weapons."
Monk Player: "Oh ****."
You may end up with a Flurry of Misses.
Don't you mean a Flurry of More Misses? Monks aren't noted for hitting often as it is.
Damn, I hadn't noticed that - good point!
While three trip attacks at -4 penalties may not be the most effective, it does give one the chance to try a trip first, and if it succeeds, take two attacks with a net of +2 bonus against the prone target. Three trip attacks at -4 against a single opponent has a better chance of succeeding than 2 trips at -2.
Also, I'm not looking to debate the usefulness of the combination, just its legality. Does this combination violate the spirit of the RAI by stacking FoM with TWF? Does it violate RAW?
Does this combination violate the spirit of the RAI by stacking FoM with TWF?
IMO, no. When the wording of two abilities (FoB and FoM in this case) are different, I'm generally going to have to assume that difference is intentional unless that results in something that's obviously broken or too powerful. In this case, IMO there's absolutely nothing unbalancing about using FoM with TWF, with non-monk weapons, or while wearing armor. Go right ahead. Others may disagree, which obviously is their right.
Does it violate RAW?
Absolutely not. Regardless of how one may feel on the RAI, the RAW is crystal clear. When you make a full attack, you get extra attacks via TWF (and improved/greater TWF). "As part of a full attack", FoM allows you to attempt an additional combat maneuver at a -2 penalty (but using effectively full BAB rather than 3/4 BAB, although note that the full BAB only applies to the extra maneuver(s) from FoM, not your other attacks). Higher level MM Monks may attempt extra maneuvers if they wish with additional penalties. Not much room for interpretation there.

A few more notes:
As alluded, the TWF penalties will also apply to the extra maneuver(s) from FoM (since they are still "attacks"). The -2 (or higher) penalties from FoM will NOT apply to standard attacks made as part of a full attack under normal circumstances. The FoM WILL apply to standard attacks that are used to attempt combat maneuvers (like trip/disarm) that can replace a normal attack. This means its always going to be advantageous to attempt the "extra" maneuver from FoM prior to the remaining attacks in your full attack routine, since if it lands, you can continue to attack without penalty.
Also, while you're evidently planning on using FoM for trips and disarms (which is fine), note that the ability actually allows you to use maneuvers like grapple and dirty trick (which ordinarily require a standard action) along with your full attack. IMO, that's where the true power of FoM lies. Even if you use it predominantly for trips and whatnot, I'd advise picking up the feat(s) for at least one of the standard action maneuvers as well. Options is power after all.
