We should separate the use of teleporter in two ways : the vm mode and the terminal mode.

• the terminal mode, student can use web terminal and vscode devcontainers to have a proper and common environment. It's attended for the student that can handler this approach (internally CDA, and advanced formations).
• the vm mode, student will all have preconfigured full fonctionnal windows manager (with vscode, terminal, browsers), and the vm can be controlled by other student / helpers / teachers. It's use webrtc (vm in browser).

Mode can be switched any time if needed without lose data or configuration, updating a local.env file.
