 Some observations:
 
- 1. Mumble is harder to use and has proven to absolutely require a
-    headset to function reliably
- 2. it is assumed that Jitsi and BBB will have similar hardware
-    requirements. this is based on the experience that BBB seems to
-    scale better than Jitsi but since it has more features might
-    require comparatively more resources
- 3. BBB is marked as having a lesser monthly cost because their
-    development cycle seems slower than Jitsi. while Jitsi
-    continuously pushes out updates on multiple components, BBB seems
-    to do a little slower release schedule.

     Jitsi, but it also requires an Ubuntu, which we do not currently
     support in our infrastructure (and an old version too, so upgrade
     costs were counted in the setup)

     starting on May 1st 2020, and by 75% for two months or more during
