I'm not going to claim to have found this - it was a great catch by Sean O'Farell (@seannyof) that I saw via his Twitter account!
While it's only one of many, many scenarios for the Windows Azure platform (and hopefully hose who attended our breakout sessions in Belfast, Dublin and Cork agree there are lots of potential business scenarios!), I do regularly get asked about Desktop/Application Hosting in Windows Azure.
Not only is it possible, but here's the link to the reference architecture and deployment guides - http://msdn.microsoft.com/en-us/library/windowsazure/dn451351.aspx
Thanks again to Sean for the spot!
