title: What are alternatives to OpenSplice and RTI DDS implementations?
body: <p>I have a good amount of experience with RTI DDS and have used it in many applications. I have recently begun to use OpenSplice to work with DDS to see if there if it is a good open source alternative to RTI. I have had these two butting heads for a while now, trying to get messages to pass back and forth between different implementations to no avail.</p>
  
  <p>What (if any) other DDS implementations would everyone recommend? I have found others such as OpenDDS but what I really want is a good DDS implementation that is compatible with RTI, supports C/C++/C#/Java, and is open source.</p>
  
  <p>I realize OpenSplice fits this description but I want ones other than that. Thanks!</p>
