In that case I have some interesting information  for you. OpenPLi also 
follows 'master' (because for many things we need the bleeding edge new 
stuff). OpenPLi and its derivatives are being used on millions of settop 
boxes. Just the "feed" servers consume about 4 terabytes of traffic each 
month.
