Its a bit of a hack but you _can_ use a frame-change callback to
manipulate any data.

See:
http://www.blender.org/documentation/blender_python_api_2_70a_release/bpy.app.handlers.html#bpy.app.handlers.frame_change_pre

A while back I started a project to host 'patch templates',
https://github.com/ideasman42/blender_patch_templates

see: `modifier_deform` example, tested and it still applies cleanly on master.

You can apply the patch then use it as a template for your own modifier.
