It'd be really nice if there was some kind of wall-like that allows movement but reduces the likelihood of disturbed sleep in some situations, particularly the hospital setting. Maybe doesn't count as "cheap" because it might want a few points of finessing: it's not really going to do anything for construction, say.
It would also be nice if anesthetized patients weren't "disturbed" by the doctor operating on them
