Another possibility would be if someone at RIT or Gallaudet that is working with software design could show them how to do it. Then release the language pack as a class project using a Open license for anyone that already has the RS client. Also send it to RS themselves to show them how to do it.
I am sure the instructors at both of these High ed locations would love to help spread the language of ASL. And besides, I know of schools in my area that uses RS for as study guides and teachers of the language that use it in the classrooms as interactive tools. I do not see why it could not be used to help the Deaf community to teach as a aid to the general public or used as a home school tool.
Just a thought.
