Each subscriber receives a custom "key" program via email.
The "key" program displays IdeaNet (tm) Books in a new tab of the subscriber's default browser (e.g. Firefox). The "key" program contains the subscriber's secret credentials, so no login step is required. The "key" program can be used on a computer running any recent version of Windows that has IPv6 connectivity to the Internet. In most regions of the world, IPv6 connectivity is available using the "Wi-Fi hotspot" feature available in most cell phone service plans.
