[ros-users] ROS & DDS

[Nikolai Ensslen]

Brian, this is a point that does not reflect my personal
experience/knowledge, but one that I heard of a couple of times when we
recently talked about the topic (at ROS for Products Workshop and our
recent meeting at OSRF), where some argued about the qualities that
current ROS middleware provides. So it is totally non-validated by myself,
which is why I said "obviously". Not sure if it was even William who
mentioned this once?

Can you say more about this point?  I'm very interested in learning about
use cases where DDS can't meet our messaging needs in the robotics /
embedded systems space.

Outstanding!
