This brings up an interesting question (well, I think it's interesting): At what point 
does it become justifiably beneficial to use a dual processor system?  Quentin, when you 
say 'serving 25-50 clients quite comfortably' do you mean it can handle 50 clients all 
logged in and working?  In Unix, memory has (almost) always mattered more than processor 
power, and with 4GB I can believe you could handle 50 simultaneous clients.  Is there 
enough of a performance gain to actually justify dual processors?
