<p>So, back when ROS was in its infancy, Willow brought in representatives from a ton of different robotics middleware projects to see if there was something that would satisfy their needs. That was about 7 years ago.<o:p></o:p></p>
<p>Maybe OSRF could do something similar, now, and have a meeting or teleconference or videochat with lead developers involved with a bunch of industry transport frameworks that it's considering (dds, zmq, etc). Then you guys could get their opinions on all
of the issues that have been brought up in this thread?<o:p></o:p></p>
<p>It could be an interesting discussion and if it's on Google+ it could make for a really engaging live hangout, too. This would involve the community in real-time and enable people to ask questions or comment on their needs.<o:p></o:p></p>

<p class="MsoNormal">Is ZeroC's ICE under consideration? It seems like it has a lot of the features people have been discussing, including encryption and compression, ability to reduce inter-host communication for topics, distributed registries, and even ROS-like
parameters (though they live on each component rather than on a central parameter server). It has a pretty similar though more general message format.<span style="color:#888888"><o:p></o:p></span></p>

<p class="MsoNormal">The answer to this is more along the lines of the original target<br>
audience of DDS operating private/closed networks. When all your<br>
communication happens within a single Navy frigate on dedicated<br>
communication wires, security is less problematic. DDS growing beyond<br>
its original audience has caused many vendors to start thinking about<br>
how to do security. A VPN is one option, but obviously many users want<br>
something a bit lighter weight.<br>
