At the risk of starting another flame-war......
I'm a believer that in today's broadband world, IF THE CG HAS ACCESS TO HIGH SPEED SERVICES IN THEIR AREA, offering that service (for an additional charge) is completely realistic. Of course, there also has to be effective wireless access points in the CG, too.
Yes, all of this costs money to setup and maintain. BUT, I do believe that campers are willing to pay for real broadband service, if the option is made available to them. In my case, we are in our coach for 7 - 8 months of the year, so broadband access is almost a necessity. for the weekend family camper, the needs or desires may differ.
