We evaluate WATER against other pluggable transport designs in terms of the following features:
- Hot-swappable: Can the transport be loaded and unloaded without recompling the host application?
- Host Isolation: Does the transport execute in an isolated environment (e.g., a sandbox) and with limited access to the host resources?
- Compatibility Guarantee: Can the host application be transport-agnostic and still work with any transport that implements the interface?
- Cross-language Deployment: Can the transport be implemented in a different programming language than the host application?
