    Your analysis only works if the requests are so evenly spaced throughout the
    day, that you don't end up with a bell curve (which is what you would end up
    with, actually).
    
    Imagine, that the default time to query for ntp would be 2AM localtime:
    
    For 2:00 Eastern (UTC-5)
    The poor server setup to field the requests would have to handle hundreds of
    thousands of requests all within a few minutes of each other:
    
    500,000 * 100-byte request / (60 seconds / min * 5 min) = 166666bytes/sec =
    1302kbps = 1.3Mbps.... This is of course assuming that the machine can handle
    all those requests:  100,000 / minute or 1.6k/s, which to my knowledge, would
    out-class all public ntp servers at the moment :)
    
    Of course, all numbers in this are just pulled out of the air :)
