In Sweden, home security offerings have been an important service on their open access networks, and start up companies have very successfully taken business away from the "big" security companies, which were slow to adapt using an IP network rather than phone lines. The network owner (e.g. the community broadband network owner) may only get a couple of bucks a month from provisioning a circuit for a home security customer, but add that to other supplemental $1-2 per month services like meter reading and you can quickly see 50% to 100% increases over the average revenue per user (ARPU) compared to triple play.
I'm still looking for the right term to replace triple play. It's definitely not quadruple play...it is more like "century play"....open access networks are rapidly evolving towards a model not unlike the Apple and Android app stores, where you will be able to buy services from hundreds of providers. We won't all buying 100+ services, but we will have hundreds of choices. Five years from now, most open access networks will probably have at least twenty or thirty providers offering various kinds of computer and data backup services because it is so cheap and easy to offer that kind of service on an open access, high performance network.
