Exactly my point: Lets use TLS and check the certificates as closely as we can. GnuGk currently checks the certificates signature (either against your own CA or the public CAs you configure) and can also check if the IP the call comes from matches the certificate. Everybody is invited to check the source code if I do it right and is encouraged to implement similar checks in other endpoints, gateways or gatekeepers!
