Also I’m off to work so it’ll have to wait till I get there, but I’m pretty sure the Safe Harbor law you’ve been mentioning doesn’t cover this. From what I remember, all they will have to do is make it possible for you to get to each machine, not make it possible for you to use each machine and certainly not purchase any special machines for you to use.
But I’m sure you’ve read it more carefully then I have, maybe you could just find the relevant sections and post it here for me.
