Motion Blurred blobbies with final gather in MR:
Normal render with FG on MR:
The key, I believe, is to make sure to have a particle cache. If you don't cache the particles it doesn't know what the previous frame was to motion blur with. I also had "visible in reflections" and "visible in refractions" on as well, since I checked the render tab in the particle object to see if it was just a "motion blur" on/off switch like geometry has. I don't know if you need to have visible in reflect/refract on for motion blur to work but I doubt it. Just make sure you have a cache and that should solve the problem. Also, make sure motion blur is set to "Exact(deformation" and not "Linear(transformation)", as linear doesn't seem to work.
One caveat: make sure you prepared for long as heck render times. That motionblurred version took around 10 minutes, whereas the non-motion blurred one took less than 1 minute. You can have fast motion blur as well, but it will be very grainy and you need to pump up the sampling, which increases rendertime dramatically.

nice blobbies btw :D

yeah got it working nicely wit me rain. sampling at min2 max3
i think that clinches me doing the particles in maya. now i just need to find out how to export cameras between LW/maya :P
