(Unnamed RPC Protocol)

• Pulls a bunch of ideals from varlink
• Encoded as two msgpack streams, one in each direction
• The stream is broken up into channels, where there is a single call and potentially many responses.
• Method names are forward-dotted paths (eg com.foobar.service.Method)
• Parameters and returns are both maps; at the application level, methods only take keyword arguments and return named return values
• Methods may return 0 or more returns or errors

For example:

# queries.gql
#!starwars

query HeroForEpisode($ep: Episode!) {
 hero(episode: $ep) {

Proof of Concept of using Python+Async to connect to a server over SSH.

Requires:

• Python >= 3.6
• msgpack
• tornado<5

Run client.py, assumes you're running ssh-server on localhost and that you can log in to it.
