| All networks are "Shared" access. AFter all, that's what being networked means.
With DSL, access is shared at the CO. What had set DSL apart in the past was that the Big Honking Switch at the Telco CO had lots and lots of capacity. They were designed and engineered to offer direct links to the big massive telco circuits that your government helped to subsidize.
Cable Internet, in it's infancy,(only 10 years ago btw) was built by private investor monies, and took advantage of the infrastructure that carried Television and was already deployed by the MSO into the neighborhoods.
What the Docsis 3.0 technology will do, is bring the same kind of Capacity into the neighborhood that the Telco switch does. Sure it's shared, but we're taking about GigabitEthernet type capicities now, not 5/10/100 Megabit capacity your used to seeing in older Docsis 1.0 CMTS'.
Docsis3.0 will mitigate that long standing shortcoming in the technology that had Cable haters and DSL lovers screaming about "shared access sucks", when all the time, they themselves rode shared access at the telco CO, but never noticed it because of the great capacity of Telco switches.
I suggest you read the white paper on the technology:
