I don't see how we could put the necessary information anywhere but in 
IP options/extension headers, if only because the TCP option space is 
too cramped and most other transport protocols don't have options at 
all.

On the other hand, TCP knows what's happening end-to-end.

So we probably want impementations to blur the layer boundaries a bit 
to take advantage of the opportunities at both the network and 
transport layers.
