Pay Toilets come to the United States!

Recently spotted in Pittsburgh: an automatic, self-cleaning pay toilet!  I hadn't seen one since I was in Paris a decade ago (at the Cite des Sciences), and was stunned to see one in Pittsburgh's "South Side" bar district.  It appears to have been in place since 2003, (news article) and is managed by Clear Channel Adshel (subsidiary of the media giant)

In September 2005, New York City contracted for 20 of its own (news article), and San Francisco has a few already.  Each toilet typically costs $0.25 to use, and about $250,000 to install, and is funded in part by advertising revenue. 

If self-cleaning toilets can appear in Pittsburgh, could it be the start of a nationwide trend in the US?
