We are about to make that much easier and also allow true infrastructure federation -- you won't have to have your nodes contact our roots directly. We came up with something very interesting. As for crypto: we plan some improvements in 2.0, but note that these days easily >90% of the traffic over ZeroTier networks (or any other VPN / overlay) tends to be already encrypted via SSH, SSL, etc. Another layer of encryption in the overlay just provides some additional defense in depth. We're rapidly moving to a world where everything layer 3 and above encrypts everything. That's why we have not prioritized sexier crypto for our L2 overlay tech. It's a bit redundant.
