Sorry to say this Kevin, but ADL is right.

At the moment, Swift3D is probably the closest thing that might work with Maya in some small way.
(export models and/or animation to dxf or obj into Swift3D standalone)

The way that I would suggest untill a vector .swf output plug is available for Maya, is to use a toon shader on a movie running no more than 30 fps, then import those frames into Flash, and choose "Trace Bitmap".

Check the Flash docs for the settings.

Sory I couldn't be of more help.

I usually just render my shots, and bring them right into Flash as movieClips, and keep the shots less than 4 seconds long.

I suck when it comes to vectorizing my bitmaps
