How about a simple meta redirect?
create a file index.html in the root of your carllyons.com domain with the following content
0 represents amount of time to wait before redirecting in seconds
Unless you don’t want users to know they’re at blog.carllyons.com, but instead to see carllyons.com at any point of time. In this case you would probably want to create frameset with only 1 frame. I would also try creating a symlink through ssh access, but some php apps break from something like that. Never tried it with wordpress though
