Well, this is a turn up for the books
<http://www.zdnet.com/blog/microsoft/microsoft-launches-contest-to-encourage-html5-content-creation-without-browser-plug-ins/8821>:
In spite of Microsoft’s backing, the contest, Dev Unplugged, isn’t
limited to apps that work only or best in Internet Explorer (IE) 9.
According to the Dev Unplugged rules, the content must render correctly
in the Release Candidate (RC) of IE9, the latest Chrome beta and the
latest Firefox beta.
Can’t say fairer than that?
