Perhaps this is too far off the mark, but couldn't the AA be written
to make calls to the EEs toolbox of functions for processing SYNs,
ACKs and retransmission?  The AA implementor might be provided with a
base class that makes the right EE calls, and would then implement a
subclass with their application-specific behavior added.

This isn't an answer to your question -- I don't see any obvious ways
of handing things around the flow hierarchy in the current nodeOS
interface spec -- the MAP_SHARED attribute proposed for mempools is
not currently in the spec.  I'll let others speak to the thread issue.
