Authenticated Services

One the the things 44net provides is a secured ham only IP space environment.  You can rest your mind that the person on the other end of the connection is a ham.

Other sites allow you transmit RF, directly or indirectly.  Such as IRLP, EchoLink, Allstar APRS-IS, remotehamradio.com etc.  And there is more potential for that.  I.e. text messages for DMR, APRS, SDR, and remotely operated stations.  Only licensed hams can transmit, remember.  We have to have some way to authenticate people and prove that they are who they say they are before you can let them do cool things.  Presently each such service has a different manual authentication method, that takes up time and resources.  At the September 2013 DCC, Heikki Hannikainen, OH7LZB gave a talk on using the Log Book of the World P12 certificates, titled "Authenticating Amateur Radio Services on the Internet."
