 # Hosted realtime audio/video conferencing
 
+> Use <https://sip2sip.info/> for now, and try limit max. 6 video participants
+
+
 ## Recommendations
 
-These hosted services are all built with Free software,
-light on resources,
-and relatively simple to later fully self-host if needed.
+Ideal would be to self-host,
+but no such solutions are readyly available in Debian yet.
+Current recommendation is therefore to use a cloud service
+built with Free software, light on resources,
+and realistic to fully self-host later if needed.
+
+Generally most reliable is <https://sip2sip.info/>,
+so use that unless you need a specific feature unavailable there.
+
+
+### sip2sip.info
+
+Login is intuitive and step-wise,
+using ad-hoc identity.
+Connect to <https://sip2sip.info/> and select room name,
+and you are redirected to a room URL
+(room URL is however long to type and at another commercial site).
+
+Media selection is done reliably
+before entering the room
+(except if you cancel browser dialog, then login page is trapped).
+
+Streaming and rendering is efficient.
+Video focus can optionally be locked onto 1-2 "speakers".
+Unknown how larger meetings are handled.
+
+Includes text chat
+(crucial in case of audio trouble).
+
+
+### letsmeet.no
+
+Login is intuitive and step-wise,
+using either ad-hoc or Feide (EduGAIN, Twitter, Facebook, LinkedIn) identity.
+Connect to <https://letsmeet.no/> and select room name,
+and you are redirected to an intuitive room URL.
+
+Media selection is done unreliably
+(not reliably detecting available devices)
+when entering the room
+(if browser dialog is cancelled you enter room in a broken unrepariable state)
+
+Streaming and rendering is inefficient
+(heavy CPU load).
+Video focus can optionally be limited to an arbitrary amount of "speakers"
+(limiting only by number not locked onto specific participants).
+Unknown how larger meetings are handled.
+
+Includes text chat
+(crucial in case of audio trouble).
+
+
+### tawk.space
+
+No login.
+Connect to <https://tawk.space/>
+which is one big "room".
+
+Media selection is done only using browser dialog.
+(if browser dialog is cancelled you enter room in a broken unrepariable state)
+
+Streaming is unreliable
+(may fail to initiate video, and video freezes after ~10 seconds);
+rendering is efficient.
+Unknown how larger meetings are handled.
+
+Includes text-based scratch-space.
