I understand that, but what is the probability of having a > 500ms 
ping/latency, or having it be that long between one packet and the next (if 
the sequence was in and of itself split)?  I mean even dialup is usually under 
a 400ms ping time... 700ms may be a much safer number, but still under a full 
second.
