We are fairly techno savvy in our household. As computer-literate iUsers, we can, for example, select music through devices that are not plugged in to the speakers from which the sound emanates, or we can piggyback devices to expand functionality.

So imagine how thrilled I was to discover the explanation for how skype works! It’s nothing more than pigeon post and wires!
