[ros-users] ROS & DDS

[Daniele Calisi]

I agree with both Ryan, Shaun and Ingo: application-specific protocols (ROS
or DDS or whatever needed) and, moreover, EASE OF USE.
Whatever things we are going to implement, should be reasonably working
out-of-the-box, tweaking/hacking/configuring should be an option only for
production phase or very big applications.
