Just to clarify, are you saying in your blog post that you can't point a bare domain to your cloudfront endpoint, and that you have to use something like wwwizer to use a bare domain with your cloudfront setup ?
No, you can specify multiple CNAME values for a single CloudFront distribution; afaik nothing stopping you from configuring 'foo.example.com', 'bar.example.com' and 'example.com' to all point to 'randomletters.cloudfront.net'
