Why is it used for telecommuting? Because it can protect the sensitive (internal corporate network) information while its travelling over untrusted networks, with the destination being none the wiser. Bridging two networks (or a host and a network) together securely over the internet has far more applications than merely telecommuting and is so effective and easy to apply, why not use it to protect your Facebook session while you're at the coffee shop?
