On a side note, 9 slaves?? Wow. Since you have been running this longer than us (obviously), did you find soon that you needed this many? Would buying more powerful machines have made it so you didn't necessarily need that many or did you need that many regardless? Just trying to get a feel for future sizing requirements. =)
