LogMein Hamanchi, free vpn?

Just came across this from logmein which is a reputable provider of remote desktop access software, https://secure.logmein.com/products/hamachi2/

I am not familiar with some of the terminology that they are using so its hard for me to make sense of this... it looks like this may be a free VPN solution, if anyone who knows more about this can take a look and give their input it would be appreciated.

Interesting. I've used logmein for years to help relatives/freinds with stuff, but I didn't know they had this. Will check it out.
