Yes, this tool would be most useful for somewhat long-living TCP
connections. One idea I had was to correlate the development of max
ack/end with number of TCP bytes sent/received over a single link.
Little development in the sequence numbers, but large amounts of data
transferred could be used as an indication of a problematic link.
However, the more I think about it, this will be a very complicated
and unreliable solution, at least when scaled up.

Thanks for your help, back to the drawing board for me :)
