Rules of the Game says no... and as far as I'm concerned, the monk is using Flurry of Blows during that full attack action, so during that full attack action, he can only attack with unarmed strikes or special monk weapons.
Let's say we have a Hasted Mnk-1/Ftr-11 with Rapid Shot, holding a dagger.
His BAB of +11 grants him three attacks... two of which he only gets because of non-Monk levels.
Haste grants him one more.
Rapid Shot grants him a ranged attack.
Flurry of Blows grants him one extra attack.
Which of these six attacks are 'part of the flurry'? Can he make two of his iterative attacks with his dagger, since they derive from a non-Monk source? Can he make his Haste attack with his dagger, since it's unrelated to his Flurry? Can he throw his dagger with Rapid Shot?
-Hyp.
OK. Let's take this from the top. This is my opinion on the whole thing (so it ain't gospel):
If he uses his dagger at all as part of his attack routine, he cannot use Flurry (it isn't a Monk weapon). So, he gets his three attacks at +11/+6/+1
If he uses his unarmed strikes but not the dagger, he can Flurry for 4 attacks: +9/+9/+4/-1
He can throw the dagger, and if he has more daggers *and* the Quickdraw feat, he can throw even more at: +9/+9/+4/-1 due to his Rapid Shot (+1 to all if within 30ft due to Point Blank Shot, as the target is most likely to be; it is a dagger, after all)
Haste, of course, adds another +1 to all his rolls and allows him to make one extra attack on top of the ones listed above at his highest BAB.
Iterative attacks from BAB is independent of the source of the BAB (it can be from multiple classes). Flurry is independent of BAB. How much you get out of it depends on Monk levels (you can't Greater Flurry just because you have a BAB of +6, for example; you need to be Monk 9 or was it 11?) Thus, whether the BAB comes from Monk levels or Fighter levels does not matter as to how many attacks he make when he Flurry. Even in the old 3.0 Flurry rules, where the number of special Monk unarmed strike attacks you make is dependent on BAB, where you get the BAB is irrelevent (you could get up to 8 primary attacks when you Flurry if you can get a 19 BAB and a level of Monk, for example).
However, *natural attacks* is something else altogether. You can use them always as part of a full attack. Take a look at the Horned Devil in the MM, for instance. You take a -5 penalty on all natural attacks if you are using them as secondary natural attacks in addition to your normal full attack action, and you only get half Strength bonus on them. You can't use a natural attack if that limb is occupied when making your normal full attack (e.g., you can't claw with that hand if you just whacked someone with a sword its holding, but you can claw with your other hand if you don't have a shield in that hand or have whacked someone with an off-hand weapon in that hand). That is the only rule in adding natural attacks to your full attack routine.
The Monk gets away with this because of that clause in the Monk Unarmed Strike entry that specifically states that a Monk can hit with a "non-limb", if you will. That frees up *all* your natural attacks to add to the full attack routine regardless of where that natural attack is. That is what make Monks with a lot of natural attacks so dangerous, and that is *before* you add in things like Rapid Strike and Improved Rapid Strike...
