Yes, but, netflow (in terms of ip src/dst, protocol type, port numbers) is a
poor way of classifying traffic that works in a fashion similar to what
we're discussing here.  P2p file sharing protocols is one instantiation..
SIP is another.  

The commercial tools for classifying deeper than header info a la netflow
are out there already, although they may not be as "slick to deploy" as
netflow (which brings its own challenges) by turning on knobs in software on
existing routing equipment.  The limitation is how motivated is the business
to deploy the gear, not whether viable equipment exists for exactly that
purpose..
