ZeroTier looks amazing and exactly like what I've been searching for. I'm testing and installing it right now, hopefully we'll be happy users soon.

One minor comment: while reading through the home page the question I first wanted to see answered was 'how do I control who joins my private network', because the technical FAQ says 'Certificates are used instead of access control lists to permit huge networks. An access control list for a network with millions of devices would become unmanageably large.'

I understand this is the technical implementation, but from a user's perspective it actually is an access control list, as on the web interface it is simply a list of IDs which can be approved or declined.

The VPN space really needed a solution like this, congrats for rocking!
