Perhaps I wasn't clear... I meant a Raspberry Pi running as the host for a bunch of USB ASICs. This way you are effectively reducing the power requirements of the host to the minimum amount. You could do the same thing with any low-power embedded system that could run bfgminer or cgminer and keep up with the network. This would be opposed to running a Linux or Windows desktop system as a host.
