Re: Non government funded muni-wide systems are OK Check out any BYO transport plan from AOL or any other ISP. Also, Verizon and Qwest have had similar plans, as does Time Warner cable.
The "bad year" could be equipment failures, storm damage, mismanagement or just plain old cost inflation. Your transport provider has no other source of revenue, so it will have to assess it's customers (that's you) for these costs, just like a condo association does, for example.
The "telecoms" have other sources, and even in Florida do not pass the entire cost of storm repair to their customers. I pay a small surcharge each month for hurricane damage cost recovery (a couple of bucks) which is shared statewide even with those areas which didn't take it in the shorts last year. Your local network operator will not have that option and will have to charge you the entire amount.
There is no guarantee of revenue, either. What about those who just don't feel the need to use the network? Are you going to force them to pay anyway (that's a tax).
