We tried that in the netherlands. Our approach did not work out that well. In all cases there's the maintainer of the hardware (cable) and a lot of "providers" on that hardware.

I'm not well informed enough to know why, but in all cases (cable, railroad, powerlines, ether frequencies) the system devolved into a state where the "provider" linked to the hardware maintainer is the dominant player still.

I'm not syaing it can't work, just that over here it didn't really work.
