== Status
Proposed
== Context
Guest VM software needs to communicate with software in other guest VMs.
== Decision
Spectrum provides two mechanisms for inter-guest communication:
- TCP/IP with virtio-net
- Cross-domain virtio-gpu which can send references to shared memory
and be used as a transport for a stream protocol, e.g. Wayland.
== Consequences
- Examples will be required on how to write applications which
communicate over virtio-gpu.
