This already exists. I saw a live (text) feed of a toilet that would post statistical information about the contents — get this — in real time.

Apparently it could also determine if you have STDs, and which ones.

[EDIT] here's the site: http://quantifiedtoilets.com/#feed Apparently it also tracks blood alcohol content and doubles as a pregnancy test. The former sounds convenient for a toilet in a bar: it will tell you if you're legally able to drive before you leave the bar.
