-Multi-party: mesh, routing, or mixing.
+# Hosted realtime audio/video conferencing
+
+## Recommendations
+
+These hosted services are all built with Free software
+relatively simple and cheap to later fully self-host if needed.
+
+  * <https://tawk.space/>
+    for casual "let's meet at a cafe" style meeting
+  * <https://letsmeet.no/>
+    for small groups of up to 6 persons
+  * <http://sip2sip.info/>
+    for larger meetings with dedicated speaker(s)
+
 
 ## Features
 
+Functionality to consider when considering tool/platform.
+
+  * topology
+    + mesh (P2P)
+      all processing at end-points, participants limited by bandwidth
+    + routing (SFU)
+      light server processing, participants limited by bandwidth
+    + mixing (MCU)
+      heavy server processing
   * stream source efficiency
     + Support [simulcast](https://webrtcglossary.com/simulcast/)
       i.e. encode multiple streams that an SFU can "hop" between
