I'm sure that if more people knew about this attribute and how to use it, it would be used in a lot more areas. It can be used within big companies that relies on strong security for their employees when they want to access company data from the outside, example mail or administrative web tools. Internet banks can also use this. They would/should only use standarized tested technology, and currently, this attribute is not fairly standarized, nor documented.
biggest bummer - IE doesn't support it. but FF, Opera, and Safari have it already implemented.
could be *very* intersting. esp. if IE got it's act together and decided to support it, too.
