Could you build this?
Partial While basic overlay drawing is straightforward, building smooth low-latency transparent desktop overlay rendering, high-performance screen recording, and local Wi-Fi peer sync across OSes requires low-level systems programming.
What it would actually take: The architecture requires C++ or Rust with Windows APIs (DirectX/DirectWrite overlays, Windows Graphics Capture API) and Android NDK (MediaProjection, SurfaceView overlays) to capture frames and draw with minimal latency. Peer-to-peer Wi-Fi collaboration relies on WebRTC DataChannels or raw UDP sockets with mDNS discovery. This demands strong competence in desktop graphics pipelines, media encoding/decoding, and cross-platform native development.
