At our hackerspace, the washroom situation was terrible. I found out there are some fuel cells that react to hydrogen sulfide! We thought about displaying whether or not it was safe to enter on an LED scrolling-message sign.
Someone where I work setup a similar app, only telling 3-4 people. Then, they built some really creepy/invasive stats into the service/page, too.
Just some advice: for each feature you add, make sure you consider how creepy/intrusive it is first. Nobody wants to be the person to object to something like this and, frankly, they shouldn't have to be.
