"With AT&T reversing their stance of not allowing VoIP applications to be used on their data network, many had begun hoping that they may also change their minds about not supporting tethering in the United States."

Keep hoping because AT&T says they can't support tethering. Rather, their network can't support it. According to AT&T, "Whenever we offer new features, we want to offer the best possible customer experience. For tethering, we need to do some additional fine tuning to our systems and networks so that we do deliver a great experience."
No word on when this will happen, but a previous spokesman mentioned sometime this year. I personally doubt that, what are your thoughts?
