OpenID provider JanRain has launched an interesting project called Demand OpenID, which lets users click a bookmarklet whenever they are on a website that they want to request OpenID support on. It's a handy, if a touch rude, way to demonstrate user demand for OpenID on popular websites.

Right now the most popular services for users to demand OpenID are Twitter, Flickr, Digg, Facebook, Amazon and Google.
