"resources from other virtio devices" would be one virtio-ipc feature
flag.  And, yes, that would for the most part have the other device
handle the problem.

But there also is "unix socket", or maybe a somewhat broader "stream",
which would be another feature flag I guess because virtio-ipc would
just tunnel the stream without the help from other devices.

Possibly there will be more ...
