I think that having a double head would help increasing the speed a lot. It can pick up two parts before traveling the long way back to the pcb.
Also, most homebrews are based on CNC machines or possibly have too much of "CNC thinking" in the minds of the designers. CNC's are more of a slow and powerful breed since they need to lug around a big and heavy spindle-motor. A P&P only need to handle sub-gram parts with a lightweight vacuum pickup head, they can be built for much higher traveling speed and accelerations.
