Either zoom has an opportunity to add a location-verification privacy nightmare of a feature, or a startup can make a zoom replacement for the unique needs of a remote justice system.
IMO the best way to facilitate this is for the courthouse to deliver an officially-sanctioned device on the date of the trial to everyone involved (defendants, attackers, witnesses, jurors, judges, lawyers), that device come with its own LTE connection, and it be a federal violation to modify that device.
In addition, the courts should NEVER divulge the location of the participants in a trial or put it into any document, as that might put violence victims at further risk.
Muting or pausing the recordings during testimony of private information, or redacting them from the recording might be a good compromise.
There is no reason to lose your privacy over this.
Zoom is blowing the doors off access, but there is appetite for specialization.
