So here's the deal. I want my phone to be able to send commands to my Mac via SMS. The idea is that I want to build an app that allows people to send commands to their Mac. I suppose I could use push e-mail, and probably will because I can send e-mails from my phone. I would rather not, because not everyone has Internet access on their cellphones. Yes, they could probably store an e-mail address in their phones, but I don't think they would like having to do that.
