I have a bunch of customers that are using the Direct Way system. They work very well AS LONG as the installers that set it up know what they are doing. The speeds are slow. Remember every time that you click on a link there is about a 1-2 second delay for the signal to go out and back (that is why T1 or higher lines seem so fast).
If it is your only optioon it is much better then dial up.
