In a short-lived game, I played a fighter in a large group of mixed Monk/multiclasses. Monk/Psions, Monk/Psi-warriors, Monk/Wizards etc. Plus a few straight spellcasters.
With all these Monks, who had Mobility? My Fighter. I also had Combat Reflexes, Iron Will (another feat someone mentioned above), Improved Initiative and so forth.
My Fighter would move freely through the enemy ranks, deliberately drawing AoOs so that they couldn't be used against others. Then they'd be facing the toughest one of their enemies right in their midst and have to draw AoOs in order to get past me to the weaker members and/or spellcasters in my party.
That was a fun game. Too bad the group didn't last.
