Animating a back and forth walk cycle

Hi,
I'm using an MH model for a catwalk scene in blender. Getting her to walk and strike a pose in one direction is easy. However I need her to walk back without using a nurbs path (makes it look like she's skating).
Has anyone else run into this problem?
I have a Mac, so editing a BVH file with BVH hacker is out of the question.
Any suggestions would be appreciated.
