My knee jerk response was to suggest that flow-tools[1] can handle v9 
output, but now that I look closer, it doesn't appear to. What you're 
talking about wouldn't be *too* difficult to implement externally, you 
just need some way to connect your SLA metrics to your aggregate flows for 
violation checks.

If you're perl-ish, the flow-tools kit + dplonka's toys should give you 
what you're after with some implementation fu.
