Could you build this?
Partial The whiteboard and chat UI is buildable, but serverless CRDT sync with group-key end-to-end encryption, peer-to-peer voice, and cross-device reliability are hard to get right without specialist expertise.
What it would actually take: A real version needs a CRDT library (Yjs or Automerge) over WebRTC or a relay that only carries ciphertext, plus a group key-agreement and rotation scheme. Voice calls require WebRTC with TURN/STUN infrastructure. Building this securely needs someone with applied cryptography and distributed systems experience, and the security model should be independently audited.
