p2p.kiwi P2P Conferencing and Screen Sharing is a simple and
easy-to-use screen sharing tool for Mac, Windows, and Linux.
It utilizes a peer-to-peer connection to share your screen with others, without the need for an account. STUN and optional TURN servers are still used to exchange ICE connectivity information.
That is not a signaling server for chat or media keys.

Don't determine whether the call is E2EE by checking whether WebRTC reports DTLS-SRTP.
DTLS-SRTP is expected to encrypt transport.
Our actual E2EE guarantee comes from MLS-managed application keys encrypting the media with SFrame.

MLS answers:
"Who is in this encrypted group, and what cryptographic secrets should they possess?"
SFrame answers:
"How do I encrypt this video/audio frame so infrastructure carrying it can't read it?"
DTLS-SRTP answers:
"How do I securely transport WebRTC media over this connection?"
