More competition: Cable companies should be forced to open up their lines, in addition to the regional Bells. Also, companies that run across Comcast and Bell systems should have to pay for maintenance, etc of those lines. If we share the lines, we also share the costs of maintaining those lines. -- God saved me from myself! Thank you, Lord, in the Name of Jesus!
What about the cost of deploying the lines? Why would comcast share lines that they paid to deploy?
Not to mention the network management nightmares that would come with this. Say the headend (I think that's what they are called) for your block is sitting there that comcast paid for. you elect to go with Time warner through that headend and your next door neighbor sticks with comcast. So now we have twice the content coming through the same "pipes". Where exactly do you expect that bandwidth to come from?
Separate the line ownership from the service. You can either be a service provider or you can own, maintain, and lease out the lines and switching centers. You can't be both.
That's the only way you're ever going to fix this. Otherwise you'll always have a monopoly in a given geographic area (barring the very rare cases where there are two sets of lines for the same "format").
