How does one export a 3D Studio animated model to OBJ format (if possible)? What will be the resulting file like? How would I read that?

If animation or scenes are needed, OBJ files won't work. COLLADA, 3DS, X3D, FBX, and STEP are better options.
Export an OBJ Sequence as an OBJ file on every frame of an animation. Exporting a 1 second animation with a 30 fps standard will result in 30 OBJ files being exported. → The Save File window opens. Select the desired file and click OK.
OBJ files don't contain any kind of rigging, so you'll likely have to manually do this in a program of your choice (Maya, Max, Blender, etc).
No, .obj files do not support animation.
You can check the .obj specification for details of what it does support.
You could potentially export one .obj per frame, but that would be cumbersome. Depending on the tools, it may be possible to export one .obj per keyframe.

Blender 2.63 can export animations in .obj, with each keyframe (as hypothesized above) being a complete .obj of it's own. Blender can handle this export func relatively quickly and efficiently. So 1, Blender is an excellent working proof of concept, and two, Blender may actually help you out code wise (it's open source and you can redistribute any edited code source), allowing you to completely bypass writing your own efficient, quick support for this operation.
