Yesterday, I learned that Hostek.com is offering free ColdFusion 10 beta hosting. It's really easy to setup. Simply add the ColdFusion 10 beta hosting to your cart, select a sub-domain, and checkout. The service is free but they will ask you for your credit card information. After your order is submitted, you'll receive an email with FTP and Control Panel information.
I set up a ColdFusion 10 site in about 5 minutes (mostly waiting for my email). The one page on my site simply CFDumps out the Server scope.
