A Silly Thought

I have recently come across an article which talks of Nassau county police starting a pilot program of talking urinals which automatically warn users to take a cab if they have been drinking.

Is there a market for a urinal based analyzer for "simple" but useful things such as testing for diabetes (among other things)? If installed in malls, revenue could come from the ads on the "For further diabetes workup, you may want to contact Dr. ____" cards. Hopefully the benefits of diagnosing diabetes early and lower testing costs would outweigh the potential ethical concerns...
