People have asked, as I did, how many R909s can the SmartHub handle?

I have 8 with plans to get 3 more to use all 11 USB ports. I am using it with an EVGA 1600W PSU that has 9 VGA ports and with special cables, use the 2 CPU ports.

Since there is plenty of CPU and RAM available, maybe a USB hub will give a few more R909 slots, with an additional PSU to power them.
