Am I missing something here, or can I start making money by sending passwords to people over the internet, so they can configure their own VPN?
Some things come to mind:

1) most general users don't know what a VPN is and barely know how to configure their networking. This does make it easier for them.

2) basically, besides the password, they are providing the encryption that is often needed for a secure connection in a wireless situation. Not everyone has a company that has a VPN setup (you usually need a start point and finish point with a VPN). It looks like they are making their VPN available for users in a wireless cafe (or other wireless location) that goes: cafe -->HotSpotVPN start ---> HotspotVPN end--> Internet. The point is to protect the connection in a unsecure place (the wireless open areas). Not a bad concept when you think about it.

3)lastly, this seems targetted towards consumers rather than business (as is pointed out at the end of the article). It would tend to go in hand with point 1.
