I agree on that.

One could reasonably argue that the attempt to solve the communication
problem in a relatively application-independent manner is doomed, and
that application-specific protocols are the way to go. Some people may
dismiss that as unrealistic, but I would argue that
application-specific protocols are the IETF approach, and that it has
been fairly successful, so far.

That said, there is a question of what the basis for such developments
should be, or, in other words, whether the protocols in the DDS family
are a better foundation for robotics applications than base-level

I guess answers to that question will be influenced significantly by
whether you're coming from an enterprise environment, or from an open
systems environment.
