I'm not sure there will be very many of those.  I would have thought the folks 
who turn-off Nagle are  typically doing small sends.  If they were not wanting 
to wait to aggregate their small sends into MSS segments, or wait for the RTT, I 
doubt thet are looking to wait to aggregate to something larger than the MSS.
