Steve,
Here in the town I live in they have a program for as you put it, "high functioning retarded". It's called Rham. The people live in basically a group home with a responsible adult as sort of a home mother or father. The program has been around for at least 30 years that I know of. They have their problems but for the most part the program is highly sucessful. If you would like I could pick up some information on it and send it to you. Maybe you could get this type of program started there.
