I've been working on a CFlow based perl script that does just that in addition 
to a whole bunch
of other things.  I've had reasonably good results taking the mindlessly simple 
approach of using
the 5-tuples to look for matches.  I simple exchange the SRCIP <-> DSTIP and 
SRCPORT <-> DSTPORT
and look for a match in the recently seen flows.  So far I've been able to 
match about 90% of my
TCP and UDP flows.  Also, I'm currently *not* doing anything to match up ICMP 
with TCP or UDP.
That's the next step.

I'll send out my script when I'm done with it.
