Could you build this?

No Writing a low-latency virtual display driver with hardware H.264 RTP/UDP streaming and legacy OS X 10.9 OpenGL client rendering requires deep systems, display driver, and low-level networking expertise.

What it would actually take: The solution requires an Apple Silicon virtual display driver (using CoreMediaIO or DriverKit), a low-latency VideoToolbox H.264 encoder, custom RTP/UDP packetization, and an Objective-C/C++ client compatible with OS X 10.9 Mavericks using legacy OpenGL pipelines. The hard part is eliminating latency and jitter across network transport while managing undocumented display APIs and legacy macOS binary backward-compatibility. This demands specialized knowledge in macOS kernel/driver programming and real-time video streaming pipelines.
