Unexplored libswarm topics

Comment on this Gist with any present or potential concerns regarding the design and use of libswarm.

How to pass configuration to a call like Attach. When attaching to a Docker container, various options can be passed: stdin, stdout, stderr, logs, stream. How would this be done?

• CLI-style args on the message (e.g. ("--stdout", "1"))
• JSON blob as the second arg (e.g. {"stdout": true})

How to expose actions that are specific to a service. For example, Docker containers can be paused/unpaused.

• call Spawn on a container where the first argument is "pause"
• call Set with a payload containing something like "paused: true"
• add two new verbs to libswarm

Enabling/initiating direct communication between two remote libswarm services. For example, linking two Docker containers, possibly across hosts.

To me, this would seem to call for a global addressability - URL-style - of libswarm services (within a network). Perhaps I send a message to one container telling it to "link" to swarm://other.service.hostname/path/to/container.
