ZeroMQ integration for external Python kernels #61
Description
Implement ZeroMQ integration for connecting to external Python kernels and environments.
Current State: Pyodide-only runtime execution
Target: Connect to arbitrary Python environments via ZeroMQ
Implementation Tasks:
- ZeroMQ protocol implementation for runtime communication
- Kernel discovery and connection management
- Message routing between Anode and external kernels
- Support for Jupyter kernel protocol
- Container and remote runtime support
Benefits:
- Full Python ecosystem (not limited by Pyodide)
- GPU computation support
- Native library access
- Existing Jupyter kernel compatibility
- Containerized runtime support
TBD: ZeroMQ message format, kernel discovery protocol, container integration
