Yes, but it tends to be a group of people on one cable (perhaps everyone on one street, or a few streets), not every customer for the ISP is in that group. *Part* of the path between you and the ISP is shared, you don't all have an individual, isolated, connections. -- (This box runs Centos 5.0, my others still run FC 4, 5, 6, & 7, in case that's important to the thread.)
