Hugely annoying, yes. The gold standard for ROS multimaster is definitely
when each individual robot looks exactly like a non-multimaster robot, and
can be added to the multimaster system with no modifications to its
underlying launchfiles, topics, diagnostic outputs, TF frames, etc. But
that obviously requires some sophistication at the robot boundary to handle
translation. And it gets interesting in sim, for.... well, a variety of

No one has released an end-to-end solution yet, but we're working on it too
