I should have said "for which a variety of solutions in a variety of
places - OS, application, API, protocol - exist..."

The primary point is that this isn't owned by communications layers.

The point is that it can be solved in TCP or at the transport layer ALSO. It's as good a place
if not better (from the co-ordination point of view and from the sender state visibility points of view). 
Let me ask the question: Can you elaborate the reasons why doing it in TCP is not a good idea? 
"A variety of solutions in a variety of places" is not a good position to be in, we want the right
solution in the one, correct place, with the least possible disruption to the server community.
