Is it possible to receive SMS with the Messages beta for OS X? I feel like I've read 7 or 8 different articles on the Messages beta, but I'm not seeing my question's answer.

So, is it possible with Messages for OS X, to receive SMS texts sent to my phone number?
No. Messages beta works like it does on the iPad and iPod Touch. You can only message other Apple iOS 5 (or Messages) users.
