Jeff-
I'm new to this board, but your subject caught my eye. I work for a telco consulting company. We design both fixed and wireless networks. From the way the industry is moving, my humble opinion is that you are correct. You will start to see (within the next 1-3 years) advertisements for wireless data transfer. My company has already started work on several fixed wireless networks (which is what you are describing). Initially these will all be targeting small to medium businesses, no one is targeting households anytime in the near future. However, once a market has been established in the business areas, like in mobile telephony, it is my guess that companies will start to expand their focus on residential uses. But this won't be happening for many years. Hope this answers your question.
