Could you build this?
Partial Creating a multi-transport protocol library across 12 distinct networking protocols (including WebRTC, gRPC, and WebSockets) with streaming and secure sandboxed code execution requires deep systems and networking expertise.
What it would actually take: A production implementation requires native Ruby bindings or pure Ruby clients for gRPC/Protobuf, WebRTC data channels, and WebSockets. It also requires secure multi-tenant execution sandboxes for 'CodeMode' and an architecture handling bi-directional multiplexed streaming across heterogeneous network protocols.
