(1) Teams allows to connect without an user account, but there’s many required steps in order to do so.

(2) It is technically possible to reuse the same link for many sessions, but accountability is lost in the process.

(3) The physical location of data can be determined with a specific agreement with the supplier.

(4) The maximum number of participants in OpenTeraPlus is voluntarily limited because of the secure architecture and the mental charge for the host (clinician) to manage an active multi-participants session

(5) Data storage of sensitive data such as videos on an external server implies multiple legal and ethical issues.
