The Tempest gets the ability to attack with both weapons during a Spring, and the name "Tempest" kind of does imply a lot of movement.
As far as other TWF classes, there's the Invisible Blade from CW (specific to daggers) and the Daggerspell classes (also obviously dagger-specific). Nothing else jumps out at me, though I'm sure there are a few organization-based TWF classes in more esoteric sources. If you want to play a slow TWF character with two bigger waepons, it's good to stick with fighter and maybe go for some of the Style feats in CW.
