We have not yet added any specific distributed fluid support with Houdini, though we do have many interfaces for Houdini that should provide the flexibility to do so (hrender, hython, mantra, hscript). If there are any specific fields or tweaks that you see should be done to provide streamlined support for this features, please send it over to us. We can be reached via this forum or directly at support <at> pipelinefx <dot> com.
