[launch] Multi-machine Launching

[matt-attack]

Feature request

Feature description

Add a way to launch processes on multiple machines using ssh in a fashion similar to the old launch system. Would allow for the launching of more complex systems.

Thanks for the feature request, it's on our todo list, but not something we'll probably do in the near future on our own.

Hello everyone, which is the status of this feature (also mentioned here)? Is this already supported? I couldn't find any doc about it...
Thanks!

@m-morelli to the best of my knowledge, execution across multiple machines is still a work in progress. See ros2/design#297 and ros2/design#272.

Does anyone know anything about the status of the feature?

I'm looking into implementing this. I've discussed this with / am in communication with those who worked on the designs linked above (@mlanting and @roger-strain).

Apologies, as it turns out, I will not be able to continue work on adding this feature in the near future. Hopefully someone else can take it on.
