I think your proposal to fulfil the interfaces in rcl using SDP doesnt take into account whether or not this daemon is running.

Exactly, as fulfilling these interfaces does not require a daemon, but it will work with ros2cli's daemon.

I cant speak for Dirk, but I got it mixed up with SSDP (Simple Service Discovery Protocol)

[/quote]

There are quite a few discovery protocols out there, I'll switch to using full names instead of acronyms when describing approaches.



I will create the pull requests that will expose subscribers and publishers per node and post them here since there does not seem to be any objection using DDS' Simple Discover Protocol. Then I will demonstrate that capability with `ros2cli node info` verb.
