Actually I'm toying with an idea to get around that limitation...
I'm going to split the manifold in half and plumb it to an intercooler. Once I have a way to cool down the hot air, I'm gonna throw the small pulley on. I'll connect a boost controller to the bypass valve and voila! Full boost at low rpms from a JRSC!!
I theory this isn't efficient because the JRSC draws more power the faster you spin it, but by using the bypass valve to limit boost at high RPMs, it will reduce the load.
I saw a Honda guy do this with a Rotrex supercharger. It was weird because as he would get into the higher rpms, you could hear a bunch of air venting limiting boost.
You also get the best of both worlds, no lag, controllable boost.
BTW, I know that the bypass valves operates on a vacuum. I'm just going to get a large vacuum resovoir and connect that between the bypass valve and the boost controller.
