Satellite has had FAP (Fair access policy) for years. When we had it, we couldn't get DSL or Cable at the time, we could only use like 256 MB and then it would slow to a crawl for a day or two. Working on computers it wouldn't take long for me to pop us over the limit just on Window's update for a fresh install. It was expensive and like someone else said a cloud would come over and bam there goes the internet.
We now have AT&T DSL and although I'm not real happy with it, it is better then satellite. If AT&T puts a cap here I may be in big trouble because I do download 1 - 1.5 GB files quite regularly.
I do think Fiberoptic is the way to go.
