How can we provide Internet services restricted to amateur radio users with reasonable guarantee that non-hams do not gain access to the services, without an awful lot of manual work by the service provider and mailing license copies for every service? Current practices, alternatives, a proposal for better future implementation of distributed trust using X.509 certificates, and a demonstration of an implementation for a web service.
There's a catch, though. Due to a surprising event I won't be able to fly to Germany myself this weekend. Fortunately Erik Finskas, OH2LAK, has agreed to act as a proxy and present my material there! Not a bad deal, since he happens to be a seasoned professional in the right field, and has applied the presented technology both at work and in the linked UHF repeater network in Finland.
