in my experience
I live in a pretty nice neighborhood in Northern Virginia in a recently constructed 'planned urban development' (PUD). This particular PUD has a few thousand homes in it and dwelling within them are a lot of dotcommers because this area of the country is a major communications hub housing such companies as Worldcom, AOL, Exodus, PSInet, Adelphia and Verizon. In fact, all of these companies have facilities within 5 miles of my house and I can almost see Exodus from my window as I type this. Not one of them is able to provide high speed access to me. Maybe I should break into Exodus with an ethernet cable in hand...
