Given this uses the Raspberry Pi firmware interface, having 
rpi/rasbperrypi in the name is sensible IMHO, but the IP is technically 
from Broadcom AFAICT, so using a bcm2835 prefix wouldn't be far off.

Ian, I am really having a hard time following all of your frequent 
submissions, would you mind waiting for feedback before spinning new 
versions?

Thanks!
