Re #2, I don't think its fair to count EC2, Github, or Heroku, unless you're also counting any shared hosting that lets you run PHP. I think what Steve was referring to was people paying for hosted versions of specific pieces of open source software, e.g., a hosted version of SugarCRM, not the ability to run open source software in general. It was still prescient though, because we're starting to see that. For instance, you can do this with Azure + SugarCRM.
