Why are you unlikely to have VDSL to your home in the near future?
What will be an ideal response?
I am unlikely to have VDSL to my home in the near future because of two issues: distance and fiber optics. The distance requirement for VDSL is 300 meters from the DSLAM, which will limit many home users, while the fiber-optic limit has to do with the fact that most VDSL suppliers in the United States (this may vary elsewhere) use fiber-optic cabling to increase distances. Fiber-optic service is not widely available to home users.
