It's more or less the same underlying approach as Hamachi: L2 virtualization. The execution is a bit different, and it's designed to be more sysadmin-friendly to enable its use as something like a cloud backplane network. As far as the future goes, I have different and I think broader goals. VPN is just the first application. I have others in mind.
