Seriously? You're missing the point. We're trying to get the OP connected. Slippyblade is just trying to break it down by saying to setup the computers for connecting to one another, it makes no difference if you are setting them up for a paid service, or directly connecting them. The requirements and most of the configuration of the hardware is the same.
And how does your definition apply to say a printer? It has an online button. Are you trying to tell me that my printer I bought back in 1984 connects to the internet or electronic information via a subscribed service? Wow that's cool. And I thought it could only print. (And even newer printers have an online button, btw)...
