NetFlow output plugin?

All, We're successfully sniffing out 100Mb connection (and getting good data too) with Snort 1.7 - congratulations to all for a great product. In case anyone's interested, we're sniffing 7k packets/sec (30Mbits) on a 256Mb PIII800 (Compaq DL380) at about 15-20% CPU usage. We're going to try a 64-bit PCI gigabit card at some point, hopefully before we move to a Gigabit connection (eek!). Anyway, my managers like pretty graphs so I've been investigating the possibility of writing a preprocessor that will do things like top-N hosts and bucket-sorting based on packet size/subnet/port number/etc. The thought occurred to me that the best way to do this would be to have Snort generate Cisco NetFlow stats and use some of the many tools available to pull that data out. Has anyone thought about that, or should I give it a look?
