And that's exactly why we developed JavaPVM, a Java native methods interface to PVM. We use it to support inter-process communication between Java clients and higher-performance applications like flight and space system simulations. Though we are using Java for more things, we currently have our aviation simulations in C/C++, a DataRouter in Java talking to the simulation through the PVM daemon (via JavaPVM), and several Java applications receiving data from the DataRouter.
